Here we have a 1957 Omega Seamaster with the 34mm stainless steel case. It is the reference 2759-11 SC which has the beefy lug design and press fit back with washer inside. This variation has an aged silver tone dial with the applied, facetted coffin hour markers. Below 12 is the applied Omega logo and the signing below. Above 6 is the stylised Seamaster text. The hands are of Dauphine style in the silver tone with the tapered central second hand. To the right-hand side is the original crown with Omega logo. The case back has the faint ‘Seamaster’ text to the top and ‘waterproof’ to the bottom. The inside of the case is marked with the reference 2759-11 SC 2761. The movement is the manual wind calibre 420 which is shockproof. It has been recently serviced and is keeping very accurate time. The watch is presented on an Omega beads of rice bracelet, which is well sized.

The dial on this example is a silver tone which has darkened with age. It has the speckled patination with a few darker spots of ageing. It provides a simple and clean base for the hour markers which provide the main talking point. They are a beautiful facetted coffin/diamond shape with the sharp, angular edges. They are applied to the dial, providing a pleasing texture and depth. There is a subtle balance to the markers with the quarters having the double facetted design. The classic applied Omega logo sits below 12 with the black Omega signing, whilst above 6 we have the stylised ‘Seamaster’ font which is a classic feature within this period. The hands are the classic Dauphine style in the silver tone. The central second hand has the elegant tapered design.

The case is well proportioned measuring 34mm x 34mm. The beefy lugs extend the total lug to lug length to 42.25mm which adds to the presence on the wrist.
The bezel is round with the polished finish, which falls away from the edge of the dial to meet the sides of the case. There is a subtle bevel before it meets the sides which is a neat touch. It holds the original acrylic crystal in place which has the Omega etching to the centre.
The lugs extend from the case and have a real presence with their wide stance. They appear from the front to be added onto the case due to the cut-out line for the bezel. They taper inwards and downwards towards the wrist. The sides appear to have the central band with the bezel and back meeting it. On the right-hand side is the original Omega signed crown which has the notched design.
The case back has the polished finish with the dished edge and flat face. It is signed to the top with the ‘Seamaster’ name and ‘Waterproof’ to the bottom. Inside it has the instruction ‘Fit washer in back’ which is a common feature in this period to aid the seal. It is signed with the Omega name and is marked with the reference 2759-11SC 2761.

The movement is the Omega calibre 420 which is a manual wind movement. It has a jewel count of 17 and benefits from shockproofing. It is a robust and reliable calibre and we particularly enjoy the bridge shape to the centre. It has been recently serviced and is keeping accurate time to within +15 seconds a day, with an amplitude of 300 degrees and a 0.3 m/s beat error.

The watch is presented on an Omega beads of rice bracelet, reference No.12 1030 with 511 end links. It is a well sized bracelet which will fit up to an 8” wrist circumference. It has the Omega logo to the clasp and rounds of the watch nicely.

The watch is modelled on a 7” wrist circumference.
