I am new to the forum, and had a question on my recently purchased first Moonwatch. The watch was purchased from a reputable seller in Montreal, and was identified as a 2001 145.0022 with a 770543XX serial number. When I run that serial number through some of the online tools it comes up as a 3570.50 from 2005.

Some further research indicated that there were some early 2000s 145.0022s with serial numbers in the 770XXXXX range so now I'm just not sure what to believe!

I love the watch, I'm just curious what I'm actually dealing with!

Thanks in advance for any help.

 

Serial #77778380 purchased in 2013 new from a AD in Australia

 

How did you know the serial of this watch?

 

He is probably talking about his own watch for reference.

 

I don't know about years, but the reference number should be inside the case-back, I assume.

 

Superluminova dial. Serial in 77's. It's a 3570.50.00.

 

yep, mine.

77xxxxx are mostly 2005 if you go by Omega serial number charts. But as you can see mine was purchased in 2013

 

Firstly which online tools? ILMS only covers up to the mid 1990s and I don’t know of any other which accurately covers Speedmasters (or any other Omega model) post that. The online serial tables listed in various sources are next to useless for some models and eras, Speedmasters have been in the 77-79m region for ~20 years, immediately prior to that they were at 48m. These serials don't increment regularly like they do for other Omega series. Buy a Seamaster or Connie today, it may have a 90m serial or even an A0 serial, buy a Speedmaster it will likely say high 78m or maybe low 79m.

Secondly, the OP is getting confused by case number as seen in the caseback, here 145.0022, and PIC, in this case 3570.50.00. As mentioned above, if you have a Hesalite crystal Moonwatch produced from around 1996 up until the screwed bracelet suitcase model in ~2013 (with either tritium or SL dial) it will have case number 145.0022 and be described as a 3570.50. You might raise an eyebrow at my mention of tritium dial but the first year of 3570s were thus equipped. AFAIK the current suitcase model still has a caseback with 145.0022 etched on the inside, though the PIC is now the rather less memorable 311.30.42.30.01.005. Think of it this way, the case number describes the watch head, the PIC the full retail package inc bracelet/strap. I am not certain when the extra zero crept into the case number (145.0022 vs earlier 145.022), maybe when the 3590.50 model was introduced in 1989, but it was a good while back.

 

Thank you for the detailed and informed replies! I appreciate the help.

This is the site I go the 2005 date from: https://serial-number-decoder.co.uk/omega/omega.htm
I'm not certain how reliable this info is but it was the best I could find.

My apologies for the confusion, I am pretty new to Speedmasters and was going solely based on what the seller had referenced. I really do appreciate you taking the time; it looks like I still have LOTS to learn!

 

That's the wonderful thing about this hobby, the rabbit hole has no end.

I took a look at the website above, I haven't seen that before. It has many of the holes and issues the tables have but at least is easy to use. It does seem moderately useful for non Speedmasters made before 1990, prior to then the serials were more regular, so I thank you for posting that. I checked it against a few known serials of my own and it wasn't too far off on the earlier stuff. For Speedmasters, pre 1995 use Ilovemyspeedmaster.com, after that you need to ask for owners to chime in as the range is so narrow. A 77m could be 2000, a 78.8m could be 2018!

 

My former Speedmaster had a 77m serial and I bought it in 1997!
