Larger size all-English centre-seconds wristwatch in best quality 'Aquatite' case.
Heavy Dennison 2-piece 9ct gold screw back case hallmarked Birmingham 1960. Smiths Cal: 0104, 19 jewel, shockproof movement, as developed by Richard Good and others for Smiths in 1957/58. Double-roller detached lever escapement with steel escape, the monometallic balance with ‘chronospan’ balance-spring. Two-tone silvered dial with a mix of faceted gilt batons and numerals, original gilt hands, the centre-seconds with the usual red tip. 33.5 mm diameter, not including button or lugs.
I am not sure of the model number of this design (Imperial models are not well catalogued) but it is similar to the I.507 shown in Smiths 1960 catalogue, page 28, but with Smiths best quality case. 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.
NB: Despite this model being sold as waterproof, all Smiths wristwatches of this date are best kept well away from damp conditions. That said, Dennison's Aquatite case is one of the few Smiths models that I can recommend for anyone considering 'everyday' use.
In fine original condition, but with some signs of age showing on dial and case, the rear with 1960 presentation inscription to A L Malpass from BRISTOL SIDDELEY, the important English engineering firm formed from the merger of Bristol Aero-Engines and Armstrong Siddeley Motors Ltd in 1959. On new best quality light brown Hirsch leather strap. Serviced and guaranteed.
