Problem: No CK-2915-1 Bezel. Solution? Make one!
I saw that you are quite involved in some Speedmaster Websites and you seem to be an expert.
I have been collecting vintage Speedmasters for about 15 years and last year I found a CK2915 in Hong Kong. Unfortunately the bezel was missing, so I decided to build a bezel on my own. After having spent 12 months and after having persuaded a dozen friends to help me I am finally there!
THAT is SO COOL! That's great!
What do you think (see attached pic)? You can compare the typography with the model printed in "Time Capsule"!
Now, CK2915's are not my speciality (I only own a CK2915-3 which looks like a CK2998), but your bezel looks really REALLY close... The Typography does look off a little bit in side-by-side comparision with what I have on hand here.
I took my typography from the OMEGA "Time Capsule" and from an old OMEGA Speedmaster ad. I guess the first bezels must have been "hand made". Your picture shows much deeper numbers, possibly engraved! The original bezel was etched only a couple microns deep, by the way that's why most bezels are completely worn out). Using the Replica bezel was a "no no" for me, because it looks way too modern and it is too big. It gives the watch a totally different appearance.
My nicest chrono is a 19--s NOS . Don't tell anyone about that ;-)
I hope that's acceptable! =)
