That is a really unique font on your date wheel. Can you give any other color?
If not mistaken that’s a 2500D movement date wheel
Francisco is correct. :-!
I have two 2500 Planet Oceans (...or should that be "Planets Ocean?") :think:
First bought in Nov '06 (C), and the 'new' one (D) acquired a few moths ago from a fellow forum-user, which he bought new-old-stock last May (2016) with full warranty.
The 2006 one had full service at Omega OB this year. Both are excellent & I can't notice
any difference in performance whatsoever betweeen them. IMHO the C vs D issue is overblown.
However, the datewheel for the 2
500D movement with the triple escapement is different & has large serifs on all numeral 1s, (10, 11- 19, 21... etc), the 4 is sharply pointed at the top, & the 2 has a straight diagonal line, all like the wheel on PO 8500 & since.
Please excuse borrowed pic, C left, D right :
The pic you commented on is of the latter, from 2016.
Excuse for a few more, showing D font ...
.... and my 2006 (2500C font) now with new bezel, & hands after Ω service (note the red tip of seconds-hand not started faded to orange - pink, as they do when after years of UV affects them) :
(in Kyoto)
'b-)
Hope some of that was useful :roll:
