The -74 caseback should not be on serial numbers that late.
Well according to William, 39 mill is acceptable for 74's and 76's.
What is the latest serial number in your database for a 74?

Sometimes one cares for any detail, what is kind of necessary, especially if it comes to high price watches.
But if you have a real beauty like this in your hands, I don鈥檛 know, if it is necessary to ask for any detail of its past..I would take her even with a lifted butt...and I won鈥檛 care..(ok, depends on the price a little..馃槈)

The latest -74 I have is 32288XXx with no extract date and oddly a step dial. The bulk of -74's I have recorded are 31.3-31.6m many of these are backed by extract. This watch is a true anomaly for various reasons. (granted this does not include the various un extract watches with 39.m and c3 dials marked 74 which I have 4 in the DB.) 32.2 is an odd number and it having a step is even odder.

The -76's are all 39m starting with a verified extract of 9/76 with 39.184m the last I have with extract is oddly yours with an extract of 39.925m which corresponds with late 1977 ( 9 or 10 of 1977 is my guess) production as noted by your c3 dial 馃槈 of the ones I have with extracts they are all in order. I have one later one by about 1,000 numbers with no extract.

I have a bit of a working theory on the 39m watches with -74 casebacks... allmost all of these seem to have the later dial as well and some later bezels, additionally the -74 stamping seems a little weird. As these serials almost always predate the c2-c3 change over that I see in no question watches it tends to lead one to draw a conclusion. Why are these late 76 early 77 watches the only ones that appear to have the later dial, when the bulk of my data shows serial in order production and a hard change over date of the dial... My guess is that in service they received new casebacks for some reasons from stocks that had the weird -74 stampings and received the current dial as a service dial, which could have happened all the way to 1990.

There is of course no way to prove this and my data set is large enough to formulate theories but not enough to be conclusive in any way.

Looking again to the first foto of the caseback, I'm thinking the -74 is done later on. Font looks different and the "-" is not accurate. In the second foto of a members caseback it looks different. As well in my 74 it looks as it was made in one step:




But it is HF stamped on OPs caseback. As far as I remember 74 was the last made HF cases, isn't it?
The 145.022-76 was the last reference with HF cases.

Just out of interest, do you have pictorial evidence of correct examples of -74s with extracts showing 31x serial numbers and production dates of 1974/5 onwards?

I believe 2 have extracts associated with them.

Thanks, that's interesting. Sorry for going off topic. I only ask because I personally have never seen that combination of serial number and production date on an extract, even though in principle it's valid for -74s.

Thank you all for interesting dial-discussion.
As I understand the C3 dial have the long 芦S禄, and the C2 have the semi-long 芦S禄.
The seller of this watch claims it to be original.
It鈥檚 a 145.022-76, ref 37870xxx,
From 1976.
C3 dials startes as mentioned in august/september -77.
Does this mean that this watch has a replacement dial?

That is the correct dial for a later 145.022-76. Please note the Aug/Sept 77 is my research and is not yet accepted.

37million serial number is way earlier then any -76 I have recorded, but is in range of an early 145.022-76 according to MWO. In this case while it is correct I feel that it is a later service replacement dial. 37m would put it at very early -76 production and should have the other dial. This is supported by the hand lume appearing darker then the dial lume (which looks freasher)... The dial lume on the 12 hour marker also makes it appear that it has been relumed... I have never seen the the lume on the balls touch the stick...

While hand lume will tend to look darker then dial lume, not to the extant that you see on this watch.

Thank you again, Foo2rama!
It鈥檚 really not easy to find these Speedmasters 100% correct!

Reviving an old thread.. come across this watch, the caseback stamped 145.022-74, movement serial no.39920xxx, puts it circa 78. The dial is also pointing towards 78.. Wrong caseback?

Dial is post last 1977. So the caseback was swapped at some point.

Agree, looks like a case back swap at some point. Swaps happens often . Here is my daily wearing watch also a 74 that had the bezel swapped at some point.

Welcome to the forum! I suggest you start your own thread for this question. You will get more answers, and your post is not particularly relevant to this particular thread. 馃憤

Swapping/finding the correct seen as acceptable I presume. Are correct bits easy to find?

Can be a personal preference, I found a mint perfect correct DNN bezel but left this beaten up one on as it is currently on the wrist daily. I don't mind replacing incorrect parts for period correct parts. I have bought a watch with a box of original parts that were replaced at a service and put them all back on.

Has anyone recorded the transitions from one dial to the next?
On the 145.022-76?

Yes Sept 77 was the change in the S in Speedmaster. The only change from once the step dial stopped being used in early -74 models untill the 80鈥檚.

I looked at about 100 years extracts and recorded the dial type and delivery date.
