So.... How is it possible to fit a later replacement steel bezel on this 2915 ?!? Or simply what is the reference of the actual bezel mounted on this 2915 ?

I don't know if the new bezel can be used as a direct replacement but it can be made to fit with some modifications.

I don't know if it "should" or "shouldn't " but in my experience,

It does!

(W/O modifications)

Interesting.... I asked my watch maker to fit such a bezel on my 105002 and he told me he hasn't succeed, the bezel was too large (inner diamteter). What kind of "modifications" have you done MSNWatch ?

@Spacefruit : you had fitted a replacement directly on a 2915 without modif ? Do you have pictures ?

I am currently looking for a substitution to an original bezel on a 2915, I'm very interested in a solution.

Or maybe someone has a Base1000 bezel in stock.... ???? ::rimshot::

Or may be I should just check another watchmaker....

Best

I haven't done these mods - don't like them but these bezels can be filed down to fit.

Outer diameter is different. Inner is the same.
Both outer and inner dimensions are different, but the bezel can be modified to fit.

Also re the Hippocampus, I believe they all came originally with a Hippocampus engraved lightly on the case back. Period advertising material suggests this can be easily removed to make way for a personalised engraving. The case-back engraving on pre-moon speedmasters remained very light for this very reason, hence the commonly seen worn case-back.
It would seem very unlikely Omega would make two versions of the model - one with and one without the hippocampus.

And how would you do that? Cause i pr茅sum茅 that the inn茅r diameter of the old one is smaller than the replacement one...

Yes the modern replacement bezel has a larger inner dia. I'm no watchmaker, but I have seen one fitted to a 2915 by Omega Bienne which had the underside of the bezel lapped (not sure if that is the correct term??) that is the metal was deformed with a tool like a small chisel all the way round, in order to push some metal material toward the centre so it would interfere with the lip on the watch. Sorry hard to explain.
I have also seen one glued on but not sure that's the best solution.

Oh my... won't be easy for sure. I understand why my watchmaker didn't succeed.

Really, nobody has a base 1000 to sell ? ::rimshot::

:whipped:

No, this is not correct, even inner diameter is different


PS:sorry, I did not scroll/read down far enough to realize this was already answered/corrected...馃槦

I was just thinking, how the hell is it possible that my 2915 has actually a "classic" bezel of modern speedy ? I don't think the last watchmaker that worked on it svejse-png.104458

Agree with Ash opinion regarding the caseback , also think the engravings have disapeared with time and use

Also re the Hippocampus, I believe they all came originally with a Hippocampus engraved lightly on the case back. Period advertising material suggests this can be easily removed to make way for a personalised engraving. The case-back engraving on pre-moon speedmasters remained very light for this very reason, hence the commonly seen worn case-back.

Actually that does not fit my research and observations.

I have found that Omega did indeed fit several executions of caseback to the 2915.

The very first caseback, fitted to the 2915-1, with speedmaster around the edge, does not appear to have ever had a Hippocampus etched into it at any time. All subsequent ones do show, to some extent or another, a Hippocampus.

Chaps

The 2915 did indeed come with a number of case backs, I have one with a very clear hippocampus and the script (2915-1) but have also seen them without. They exist in both executions and both perfectly legitimate.

Here is my 2915, it has also had service replacement hands and bezel aged (also slightly later circa 1959 tropical brown dial) this is one of the few which exist with extracts, 2915-1 which was delivered in 1959 to Switzerland

See my avatar for a 2915-1 with nice unworn hippocampus. 馃榾
