Jumbo Board-Script, the 1981 edition

Since last week, I’ve been the very proud owner of a beautiful Omega Speedmaster BA345.0802 (42mm diameter and 13.7mm thickness) from the 80s. This is the second-generation 18K gold Apollo 11 tribute Moonwatch, released after NASA requalified the Omega Speedmaster for the upcoming Space Shuttle missions in 1978.

Omega released the BA345.0802 (as well as the white gold BC345.0802) in the winter of 1980 and it is still shrouded in a bit of mystery, as some facts remain unknown. While searching for the perfect example, I gathered a lot of information, spoke with many collectors, writers, and did the obvious vintage thing: the process of elimination through observation.

So this is my personal journey, and I hope this post will help other collectors! All photos are mine unless stated otherwise.


But first, a shout-out to Aludic, also known as Speedybirthyear on Instagram. He was the one who pointed out the perfect example to me. It was a German advertisement I had somehow missed. He’s a great guy and is always happy to help you find your birth-year Speedy. I was actually looking for one myself, but I ended up going with the year 1980, as it has more emotional value to me (personal story I'm not going to share publicly) than my actual birth year. My new acquisition was produced on 17 December 1980 - less than one month away from my birthday! So it's actually a double win!


Okay, let’s dive into the details:
Summary:
1) Mystery 1: the dial
2) Mystery 2: production numbers
3) Mystery 3: leather strap version
4) Not a mystery, but a lot of fun firsts!
5) Two gold case stamps
6) German watch box


Mystery 1: the dial

Mk1 dials

There are three known dial versions: one with “Swiss made” underneath the minute track and a shorter S and R in “Speedmaster.” Let’s call this the Mk1 dial.

Swiss made underneath the minute track and shorter S and R (Mk1 dial)

Mk2 dial
Then there’s a version with a longer S and R and “Swiss made” above the minute track, as also shown in Moonwatch Only: the Mk2 dial. Mk1 and Mk2 are not official Moonwatch Only details by the way.

From my observations of all the catalogs, sales ads, auctions and magazine advertisements from 1980/1981, they all feature the Mk1 dial. From 1982 onward, we also start to see the Mk2 dial.

Various catalogs and magazine ads

This has also been confirmed by Grégoire Rossier, the writer of Moonwatch Only and he has been doing additional research. The Mk2 dials are very rare and I’m fairly certain they were actually prototype dials! These were probably produced first in a very small batch to see how it looked. A small change was made during the ongoing design process, to more closely match the BA145.022 dial (the first gold Apollo 11 Speedmaster released in 1969). On the BA145.022 dial, “Swiss made” and the S and R are very similar to the Mk1 dial.

On the left BA145.022, right BA345.802: both Swiss made underneath the minute track, smaller S and R.

I think later on Omega used the Mk2 dial in the main production simply because they already had them available. You could argue that the prototype dial should be called the Mk1, but it was not used in the first batch.

More macro shots of the Mk1 dial

All 345.0802 dials are not solid gold and do not have onyx markers, unlike the BA145.022 dial. There is no 'OM' printed on the 345.0802 dial, and it is still available as a service dial (Mk3; see below) for approximately €310 (exchange only). So it clearly isn’t solid gold, in case anyone was still wondering.

Mk3 dial
The Mk3 dial is currently still available as the service dial and has a long S and R, “Swiss made” underneath the minute track, no accent lines around the subdials and the “30” and “60” are horizontally aligned. On the vintage dial, the “60” sits above the accent line. It's therefore easy to spot a service dial and the white gold version (Rhodium plated) can often be seen in mods.

The running seconds subdial of the Mk1 dial, with '60', '40' and '20' printed more to the outside of the subdial

I came across the offer by Cambi Auctions: this is the Mk3 dial. No accent line around the subdials, 30 and 60 horizontally aligned and longer S and R.

Mystery 2: production numbers

In Moonwatch Only and all watch vlogs you read that “approximately 300 pieces” were made. The main reason for this is that Omega did not register all case numbers in the archives. Each 345.0802 has a number on the caseback and Grégoire found that some are missing in the archives. Errors were made back then, as delivery invoices were typed on a typewriter and only added to the archives days later. Some serial numbers were even matched to the same case number, so it’s a bit of a mess to get a definitive answer.

Catalogs are very useful for assessing the condition of a watch.
My watch is number A159

Razor sharp caseback engravings

I believe exactly 300 were made, because I came across a Hong Kong Phillips auction featuring number A300. No higher number has been found and this seems too neat to be a coincidence. About half of them were shipped to Germany in 1980 and the rest were delivered world wide from the end of 1981 onward (most likely most on order).

Philips Hong Kong Auction (see A300 on the box and hang tag)

Pinpointing a specific production year in the 1980s is nearly impossible without an Omega Extract, as serial numbers were only linked to the movements and the watches were then randomly distributed.

This means a lower serial number can actually be years older than a higher serial number, according to extensive research done by Aludic. Another issue with the Omega Extracts is that they do not show the actual production date, but rather the date the watch left the Omega manufacture for the distributor plus a few days before it was entered into the archives. I have seen an authentic Omega delivery invoice with 20 serials and an Omega extract showed that the “production date” of one of those serials as being five days later. So don’t be fooled into thinking that the “production date” is anywhere near the date the watch was actually assembled.

Mystery 3: leather strap version

It took Omega eight years to sell all 300 yellow gold BA345.0802s. Exactly why is unknown, but during the 1980s there was a major economic downturn following the second oil crisis, the gold prices plummeted and quartz watches were in high demand . So I think that, with its hefty price tag (around €23,000 in today’s money), it simply didn’t sell well compared to the regular Moonwatch (roughly €1,000 adjusted).

Cash is king in Germany

The BA345.0802 only appeared in the 1982 international Omega catalog because of the worldwide release. It was probably only available by special order as most were made in 1980 and Extract show it left the factory years later (again: production date is when it's shipped to the distributor). It was also advertised in the 1987 international catalog, but only available on a leather strap, reference 145.0039. This also happens to be the case reference, just to make things more confusing. Only a dozen were sold and no Omega extracts are known to exist after 1988.

The main 1982 Omega catalog

The main 1987 Omega catalog with the 145.0039, notice the location of Swiss Made on the dial!

Let’s assume Omega produced all 300 in one go, then realized after several years that they weren’t selling well enough and decided to offer a more affordable leather strap version. Since this wasn’t an additional production batch, did Omega swap some of the gold bracelets for leather straps? If so, did those bracelets become service parts or were they melted down and the gold reused?

The BA345.0802 was too expensive at the time; gold prices plummeted just after the production

4) Not a mystery, but a lot of fun firsts!

The 345.0802 was the first Speedmaster Moonwatch with a display caseback (snap-fit) and the only Speedmaster with the rhodium-plated 861L movement, featuring anglage decoration and 19 instead of 17 jewels. The very rare Omega Tridor series also has the 861L movement.

The 861L movement and it's unique finishing for a Speedmaster

Bracelet
The 345.0802 bracelet is the first gold one to have removable screw pins, making it very easy to remove or add links. Nice engineering that was lost again on the later bracelets in the 1980s! This full-length bracelet has 25 links (26 if you count the one connected to the clasp cover with the Omega logo) and has 6 removable links.

The end links have support rods, that also hold the springbar in place. This way the end link keeps its shape and doesn’t move when mounted.

5) Two gold case stamps


The case with it's sexy 80s lugs has two stamps on the lugs. One is easy: the “750” hallmark stands for Au750 or 18-carat gold. The other one was definitely more challenging. I had a fun discussion with some gold experts and only a few of them knew what these meant. Collector @wouter van wijk mentioned it's the Swiss 18K hallmark, featuring the head of Helvetia, while the “t” stands for Tramelan, approximately 24 kilometers from the Omega manufacture in Bienne. In Tramelan, a federal institute tested the 18 carat gold and upon approval stamped the hallmarks into the watch case.

Tarnish
The tarnish on the yellow gold is clearly visible and gives this already beautiful watch a unique, personal touch. This result of oxidation forms because the silver and copper in the 18K alloy react with oxygen, moisture, and chemicals. Over time this leads to discoloration of the surface. It is easy to polish out, but no need for that!

Proper patina!

The full length bracelet weighs 72 grams and the complete watch with bracelet weighs 144 grams. It’s still unclear how much gold there is in total. Maybe a watchmaker can give me that number someday when the watch is being serviced.

6) German watch box

A full set from Germany sold by Dreamwatch

The approximately 150 pieces that were shipped to Germany all came with a very specific black box with an aluminum plate on it. This plate features the Omega Speedmaster Professional print and a 3D bronze-colored caseback-lookalike emblem. The set included a numbered certificate with a photo of the watch on it. I only got the box, and it’s clearly showing its age, as the thin faux-leather lining is almost gone. It still looks cool, though! Other countries received a different or generic watch box (see the Phillips auction above).

My set and I love it!

Some more photos and observations:

Printed black hour markers on gold; no Onyx!

A3 long-feet hesalite from the 80s

The yellow gold B2 bezel is unique to this reference


Notice the finishing of the hands, seems like they have been powder coated?

Just wow! Congratulations and wear it in good health!

Awesome Speedmaster, story and pictures! I think I have never seen so nice pictures of this reference, love it!

The combination of beautiful yellow gold, Apollo XI history, 80s vibes, a useable bracelet, display caseback and hesalite crystal feels like the perfect golden Speedmaster to me! I wasn't aware of that! 😄

Congratulations again!

Incredible. Looks so nice. I'm surprised on bracelet weight. My yellow gold bracelet with all links is 116 grams. But end links on mine are solid.

Superb photography and excellent write up ... the type of stuff we're on OmegaForums for !

Please let me add-in a short story of NASA astronaut Thomas "Tom" Stafford and the Gold Omega Speedmaster. We all know, on 25th November 1969, Stafford received a Gold "Apollo 11 tribute" Speedmaster BA145.022-69 (N° 13).
Between 1970 & 1980, Thomas Stafford was one of four astronauts actually using the Gold Speedmaster during NASA training! In 1979 Stafford became an Omega USA board member and a well-known Omega watches ambassador.
In 1985, during a transfer at Dallas Texas airport, Stafford's Gold N° 13 was stolen and Omega decided to replace it with a Gold BA345.0802-84 Speedmaster.

Thank you, Alex! It does indeed seem to be a bit of a hidden gem. With only 300 examples made instead of the 1014 pieces of the BA145.022, a nicer 861L movement and it being an Apollo 11 Speedmaster as well, it still feels undervalued! Fortunately, that allowed me to close a very good deal. I'm glad I get to share the beauty of this reference.
Thanks for sharing. Great research, awesome pictures!!
Thanks for reading!

Thank you, which one is it? I think the bracelet on my Moonshine 50th also weighs a lot more, with all solid links and endlinks.

That's very interesting, I was unaware of this! That also explains why his BA345.0802 has the Mk2 dial (Swiss Made above minute track and longer S and R).

Photo: Fratello Watches

I just came across this listing from Cambi Auctions in my archives: it has the Mk3 dial: longer S and R, Swiss made under the minute track, 30 and 60 horizontally aligned and no accent lines around the subdials! I have only seen one so far, so it is most definitely the service dial. I have also added it to my original message.
