A Superb Hamilton GS 75003-3 Tropicalized Military General Service Watch with Blemish-Free Dial and Beautiful Vanilla Lume, c.1960s.

The Hamilton Watch Company is a Swiss manufacturer of wristwatches based in Bienne, Switzerland. Founded in 1892 as an American firm, the Hamilton Watch Company ended American manufacture in 1969. During World War II, production of consumer watches was stopped, with all watches manufactured being shipped to troops. More than one million watches were sent overseas.

The Hamilton GS (made by Hamilton Switzerland, rather than Hamilton USA.), replaced the Mark XI in the British Forces inventory.

What’s On Offer 

The dial is in fantastic condition, rich black, blemish-free and boasting a vanilla-coloured lume across the hour plots and original sword hands, which have aged beautifully. The Arabic numerals and outer minute track are sharp as is the Hamilton signature. 

The dial is printed with “G.S.” at 6 o'clock denoting that the watch was made for the British Military 'General Service' division and would have been issued to a non-military member of the British armed forces. The dial is completed with a brilliant white central seconds hand and encapsulated underneath shatterproof Plexiglas. 

The case is in superb condition with very few signs of light wear. The case back is engraved with information about the watch. To the centre is engraved the Hamilton “H” with Tropicalized and 75003-3 (the model number) below.  Above the “H” is engraved 150oE which indicates the magnetic shield exceeds 150 Oersted (1oE = 79.577 amperes per meter). “Shockproof, Anti-Magnetic, Waterproof” and “Temperature Compensated” are engraved around the outer edge. 

We don't come across many of these 'GS' marked watches so they are very collectable!
