More details

Heavy all stainless-steel antimagnetic case with rotating alloy bezel, the screw back also engraved ‘100% WATERPROOF TESTED 20 ATMOSPHERES.' Cal: 60467E 17-jewel movement. Double-roller lever escapement with steel escape, the monometallic balance with beryllium balance-spring. Black dial with luminous numerals and hands, including the seconds hands. 37.5 mm diameter, not including button or lugs. 

A good example of Smiths model CM.4501 wristwatch, one of the rarest of all Smiths quality wristwatches, as shown in their 1968 catalogue, page 12. This should not be confused with the smaller boy’s size Smiths Divers-type watch that it resembles. For more information about Smiths English wristwatches see the short note in my website Glossary, and my illustrated article on Smiths ‘English Wristwatches’ in the April 2003 issue of Antique Collecting.

The softer alloy bezel showing some signs of use but much better condition than usual. The crystal, with magnifying section over date (spare parts are no longer available), is also in very good clean, unscratched condition. On nearly new brown leather strap. Cleaned for its previous owner and looks to be working well, but no guarantee - priced accordingly.

NB: Although this case style was supplied as waterproof up to around 600 feet when new, this watch has not been pressure tested or fitted with new seals, as far as I know, and should not be used for diving until the necessary work has been done.
