This one of the rarest of all Omega Seamasters the Jumbo sized Omega Seamaster Bumper Automatic model reference 2657  with calibre 344 chronometer movement.

The diameter is 36.5mm excluding the crown which makes this a jumbo and is the largest of the bumper vintage Omega Seamasters.

The movement is Omegas highly reliable calibre 344 fully automatic Bumper chronometer movement. An Omega "bumper" is a vintage Omega that has a "bumper" automatic movement rather than a full rotation rotor automatic. The oscillating weight makes a partial rotation before "bumping" into a cushioning spring. This is the earliest type of automatic movement.

The two tone Explorer dial with sub seconds is totally original and untouched it has had no restoration whatsoever, its in fabulous condition with just a slight even patina to give away its 70 years. The lume on the dial and the hands is also original with remarkably no losses whatsoever.

The winding crown is original and has the early flat footed Omega symbol.

The case is in fabulous condition all we have done is a light polish  The case back has none of the case tool damage normally seen on watches from this period, its just perfect.

We have fitted a top quality Tan strap but we can fit almost any colour or style of strap you prefer, we keep most things in stock

The watch has just been fully serviced and is guaranteed to be genuine Omega in all respects. It is keeping time to within Omegas original specification and comes with a one year warranty.

This would undoubtedly be one of the most prized Seamasters of any collection.

 

A true collectors heirloom watch not to be missed.
