hi,

looking for some help on strap for my seamaster 300 41mm. it's currently on a 21mm alligator that tapers down to a 18mm deployant.

I would like something black rubber or sail cloth and rubber back to dress it down, preferably an OMEGA branded option with keeping the same buckle.

please let me know your thoughts.

cheers

Won’t be Omega branded, but Artem offers a sailcloth strap with rubber backing that is designed for the Omega deployant. If you insist on Omega branding, the Dark Side of the Moon cordura strap will fit (barely). It is thick and will rub against the case, and I found I had to be careful to make sure the deployant snapped close properly. It also has a leather backer.

once I got the Artem, I sold the DoM strap, because I feel the Artem is better.

The 43.5mm PO is 21mm Lug width
The 42mm is 20mm Lug width
The 45.5mm is 22mm Lug width

A big ol’ +1 for Artem sailcloth straps. Current versions of the Artem sailcloth are some of my favorite straps; a great look on a number of different watches, deployment-ready versions available with 21 mm an option, very durable yet comfortable in a variety of different watch wearing scenarios…my 43.5 PO on a 21 mm Artem deployant

The black rubber strap from the ceramic SMP fits the heritage models.

At least one person on watchuseek has also put this strap onto the bronze-gold variant:

Someone has managed to make the 21-mm SMP dark blue chronograph rubber strap fit, although it requires curved spring bars and possibly some modification. May want to go over to watchuseek forums and look through the last five pages of the 300mcc thread.

Here's my 43.5mm PO with the strap from my AT Worldtimer.

Should also fit the 300 Heritage as they're all 21mm Lug width.

Could be. Some of these have longer case ends on the strap and are really difficult to fit onto the heritage. I haven't seen that one tried.

You might have a point there, I didn't know the Heritage has a shorter lug-to-lug distance. Unfortunately, there's no specs on the length of the case ends.

The 300 Heritage has a lug-to-lug of 48.0mm, case diameter of 41mm
The 43.5mm PO has a lug-to-lug of 49.0mm, case diameter of 43.5mm
The AT Worldtimer has a lug-to-lug of 50.3mm, case diameter of 43mm

However, the lug-to-lug distance is not definitive, since the holes might be spaced differently on the lugs from model to model and the case diameter also comes into play. The Heritage has the shortest lug-to-lug distance, but also has smallest case diameter of them all.

Viewing the specs above, the lug-to-lug difference between the Heritage and the WT is 2.3mm and the difference is case diameter is 2mm, so a possible total offset of 0.3mm. The difference between the PO and the WT is 1.3mm lug-to-lug and 0.5mm case diameter, possible total offset of 0.8mm. So it seems there's a high probability it will work and the length of the case ends might be what makes or breaks the exchangeability. Playing around with different spring bars often yields the solution.

For example, I can use the AT straps with the same spring bars on my 42mm and 43.5mm POs. An AT strap on my SMP 75th Anniversary required thinner spring bars, and the PO Alligator strap on my WT required curved spring bars. I have yet to make an OEM AT strap fit my SMP 2265. Oftentimes the only way to find out is to try.

Thanks. I think I saw that. To me, it looked like the fit wasn't as good as what you have here, with the strap coming close to interfering with the bezel.

Yes, this strap fits almost as if it was made for this watch, and from what I understand unless you make modifications to the blue strap we are talking about, it actually does interfere with the bezel.

Rubber B makes a blue strap but I'm not sure it's the right color blue to work with the 75th anniversary, and you're left with either a Kevlar pseudo basket style or faux crocodile, not Omega two ridge.

You picked up a 75th, right? How is the family? Everything well?

Yup, got the 75th and now I get to wear it since my son recently arrived! Mom and baby are well, and definitely in the honeymoon period with the watch too!

Sounds like great news across the board! Glad to hear that everyone is healthy and happy, and I'm glad that you have something fantastic on your wrist to look at during those inevitable times when sleep is the most precious commodity in your life!

Thanks for your kind words. I'll try to post some pics soon - maybe during one of those sleepless nights.
