Omega Automatic Cal 342

Case material:

9ct Yellow Gold

 Ref 12308


Here we have a 1948 Omega Automatic 'Bumper' in a 33mm gold case,

silver dial, thin leaf hands and a seconds sub dial at 6. This watch type is known as a 'bumper' due to the design of the movement which rather than spinning perpetually, bumps off of two springs.

This was how many early automatics in the late 1940s were designed, and other watch companies also used this design. 


The dial is a soft silver colour with gold applied arabic numerals and hands. The case has a snap on back, original Omega crown and nicely shaped turned down lugs. This has a smooth polished finish and a lug width of 16mm. 


We have fitted a new brown leather strap with gold plated buckle.

Condition Report

The watch is in overall excellent condition with light ageing visible to the dial. The case has been given a light hand polish so shows only minimal wear and a small ding to the case back. The crystal has been polished so shows very minimal wear too. The movement has been serviced by us so is clean and keeps excellent time.
