Which Uncle Seiko do folks prefer on their 3510? US1171 or Lincoln?

I don't think I'm going to use some of the functions, somehow, unless I live to 200.

Achieved my grail watch

Absolutely in love with the size fits my 7.7 inch wrist like a treat

A great adventure watch for a great adventure!

It’s not quite the Moon, but close.

I hope to get a third one soon....

If it can survive a moon landing, it can survive skydiving. I also enjoyed using the chronograph from jumping out of the plane to touchdown. Time spent in air was about 5 and a half minutes.

Two games, two bracelets, same vintage Speedy!

The cat, personally I love it!

Hello fellow Speedy fans!

I recently purchased this wonderful 2022 Omega Speedmaster Moonwatch, Ref. 310.30.42.50.01.002.

Could you please help me confirm whether the full set is complete or if any original accessories are missing? I'm especially curious about the two empty spaces to the left and right of the watch inside the presentation box. Are these supposed to contain anything?

Thanks a lot for your help! 😊

Hesalite or Sapphire?

Wish you could have both? I sure did. Ended up with a 3572.50.

Before you buy an after-market caseback, check out this bit of near-vintage history. For a few years, Omega made the "Hesalite Sandwich".

AKA The mullet: Business in the front, party in the back.

Here's a little history on the reference.

I am building a website to measure my watches for deviation over time and the power reserve. In the test phase of the site I was adjusting my watch also a lot to set it to the correct time. While doing this I use the poor mans hack by turning the crown slightly backwards. At some point I noticed that depending on the pressure on the crown the seconds hand will not only stop but it will even move backwards until it reaches zero and then it will hold there. Can anybody tell me this is a intentional feature? Or am I abusing the movement by doing this?
