I have 2 vintage Omegas both automatic bumper movements. One is a 351 movement and the other one is a 354 movement Seamaster. Both watches looks similar. How about you?
Watchco assembled Cal 552 SM300 diver, 2225.80 ETA 7750 Seamaster Diver's chronograph, Cal 501 Seamaster gold-cap and Cal 501 Constellation pie-pan, all very well loved =D
Wow! Great set of Omegas. The Constellation pie-pan must be one of the best looking watch ever designed.
Not sure my latest Ploprof is watertight though! Sorry - that's not one of my best watch pictures! I'll try and do better!
Ah! AH! So that's how the bezel on a PloProf works, the balls must be sprung to provide resistance when it clicks and then the pin locks it when the button is not depressed, very cool
Yup, you've got it. Its a great system and very safe for divers as its very difficult to accidently move the bezel position and therefore possibily run out of air whilst on a dive. The bezel on my 60's sub only needs to be lightly knocked for it move (hence I keep overcooking my pasta!) Omega copyrighted the idea and I guess thats the only reason its not used on many other watches. That and the expense of manufacture perhaps. I have some manufacturers diagrams showing how the whole watch goes together if anyone's interested.
