DELUXE SMITHS ENGLISH ANTARCTIC EXPEDITION PATTERN WRISTWATCH 17J SERVICED c1953
Fully serviced and in excellent working order, a Smiths made A454 Antarctic issue pattern wristwatch c 1953. These were advertised as having been worn on the Fuchs expedition a year after the Everest one in 1953 . Fitted with a ZRC cowhide strap.
This is an early version of the watch (J/C177095) with a very thick case, presumably the type referred to when the Everest issued watches were purported to be in a new thinner type Aquatite case. The back and top of the case can be here seen at the top in the image with two in profile, above a later normal thinner type case. The case ring is like one from a later 19 jewel Everest and is very deep, but even so struggles to make up the height difference. The dial is made from a silvered metal and is pretty worn. The lume has been lacquered into place on the hands.
The case diameter is about 32.1mm. Total depth about 9.5mm. The slots in the case back are quite narrow which is evidenced by the collection of scratches. The crystal is a replacement one, the one fitted was much higher and clearly not correct. Chroming isn't tooted, the crown is the Dennison pattern one found more usually on the A404, although I'm happy it is original to the watch. The images show the balance moving, and yes it has got screws they're just invisible in motion.
The case back could be tidied on the lathe but due to the rarity of this one I've left it as original as possible.
