Russian Marine Officer's Chronometer

Bought this watch on eBay for considerably less than the current starting price.  But after making this image that's big enough for my eyes it appears that the balance wheel is all brass and that it is a solid circle, not cut and not a bi metal type.

Notice in the photo above the watch is stopped.  This way you can see that the balance wheel is one piece, not cut as would be the case with a bi-metal temperature compensated balance wheel.  Also this one appears to be all brass.

The vertical light colored bars are not part of the watch, but are an artifact from the flat bed scanner.

Another similar, if not identical watch is at:

3 July 2007 - the replies all say the watch is real.  It may be that the mainspring is compensated.  The Hamilton Watch Co. chronometers do not have a cut in the balance wheel rim which works with slight flexing of the rim.  If the "2-53" marking is a date, then the W.W. II Hamilton technology would be well known all over the world.

7 July 2007 - More responses all say it's a real watch, not a fake.

The red items are rubies used a low friction bearings.
