UK POSTAGE ONLY FOR THIS ITEM
The watch has a 17-jewel calibre 28.10 RA bumper automatic movement which is working nicely.
Later automatic watches have the fully rotational rotor. The Omega 28.10 became the basis for future Omega automatic movements, evolving into the calibre 3xx series.

The movement is fully signed and it has the serial number 11,305,140 which dates it back to 1947.
The watch measures 34mm diameter excluding the winding crown and the lugs. The case is stainless steel and it is in good condition, just a little marking to the back of the watch.

The inner case back is fully signed and it has the case reference 2658-2 which is correct for the calibre 28.10 RA and subsequent 3xx calibres.
The lens is in good condition.
The signed honeycomb dial is in its original finish with original hands, cross hair detail and very rare hour markers.
A new leather strap has been fitted.
The watch comes in a new presentation box.
