vitriol

I think t_solo_t is not an active member, so for the records here is a copy paste from his today's Instagram.

"t_solo_t Mystery solved Blue bezel 300 after considerable help from a knowledgeable collector the mystery is solved There is a small batch at the end of the line of the 300 which went primarily to South Africa with 2 others to Asia which has this genuine blue cast to an original bezel which is Tritium and Acrylic...the insert is original not from a similar Seamaster.. it’s rare 9 known"

Hi everybody, this is my first thread here, and I would like to share some information I collected over the years about Seamaster 300 165024 and 166024 bezels:





EDIT:

There are apparently many F-type (https://omegaforums.net/threads/rn-sm300-f-s-phillips-auction-geneva-13-14th-may.56782/#post-701593):
- F1 with a pointed triangle
Produced as early as 1967 and 24M serial numbers but very rare compared to C-D-E-types.
- F2 with a rounded triangle and bolder numbers.
Most common from 1969 and as a replacement in the 70ies and 80ies.
- F3 similar to F1 but without minute markers (all black but triangle and numbers).
Rarest.
- F4 similar to F1 with a broader triangle
Extremely rare, mostly on Royal Navy / Ministry of Defence.
- F5 a blue version similar to 166.073 bezel insert.

Here is a F1 F2 comparison (both bezels taken on the same picture, same scale):

Here are the 4 most common fakes:
