: C'mon guys show me some bumpers !!

: S.

I like your taste in bumpers

I also have a 1952 Seamaster Calendar

Which has this inside -- a bit rough, but functional calibre 353, one of the series of 28.10 mm calibres

My first ever vintage purchase, a 1947

With a 28.10 RA with the exposed springs

I also have a trio of bumper chronometers, two 1948 Centenaries and a 1949 Chronometer . . .

The Centenary has a 30.10 RA; the Chronometer is just after calibre numbers began, and has the smaller 28.10 RA with a fine index regulator calibre 343.

Omega's bumpers were either 28.10 mm (340 subsecond and 350 center seconds) or 30.10 mm (330 subseconds)

This is the 30.10 RA in the Centenaries

And this is the 343 with the "rg" index regulatory

My early collecting days included poor redials, including this 1951 . . . .

This is in it. . . calibre 351 with the bumper springs covered

And another poor redial in this 1954

This calibre 344 is inside with the swans neck regulator

Some refinishes are better than others, the Seamaster Deluxe, sometimes called the Seamaster Ultima in the US

Which has a calibre 352 with fine index regulation . . . .

And this 1956 Connie

And the calibre 354 inside with swan's neck regulation
