An Omega gentlemens' 14 carat gold filled automatic bumper calendar watch manufactured in c1949. This 69 year old watch is in great original un-restored condition. The case and dial present very well and the movement is running and keeping time. The bumper unit is Omega's first automatic mechanism, introduced in the mid 1940's and produced until the mid 1950's. They are efficient mechanisms, suitable for every day use. Bumper watches are among the most highly sought after vintage Omega watches. It is signed in four places, on the dial, case, crown and movement.
Dial: factory original, finished in satin silver with an outer minutes chapter, a subsidiary seconds dial and hours marked by applied gold coloured arrow batons and Arabic quarter hour markers. The dial is signed “Omega Automatic Swiss” and bears the Omega symbol. The hands are in good shape, showing some light tarnishing and the crystal is clean and clear. The dial is inevitably showing gentle patina but for its age, just shy of 70 years, it is in amazing condition, much too good to even contemplate any restoration.
Case: 14 carat gold filled, in good condition, measuring approximately 33 mm across, excluding the signed crown (replaced with a period crown at some time as with most vintage watches) and 39 mm from lug to lug. The case is signed Omega on the inside of the rear screw back cover and also hallmarked as 14K gold filled. The case shows the expected signs of use over the years but no evidence of abuse, dents or scratches of any significance that I could see to draw to your attention or any obvious signs of brassing.
Movement: Omega cal. 342 17 jewel automatic bumper movement with a serial number dating the watch to c1949. It is running and keeping time. The bumper unit is so called because the winding rotor does not travel a full 360 degrees as with modern automatics; instead it travels just over 300 degrees hitting a sprung stop or bumper at the end of its travel. It then bounces back the other way, hitting a sprung bumper on the other side. It continues to wind the watch by this hammer action. When the watch is shaken the bumper mechanism can be heard and felt distinctly but this is rarely experienced when the watch is worn. These movements were constructed by hand by the most experienced Omega watchmakers. Even when new, bumper movements were the subject of great interest among watch connoisseurs worldwide and today they remain highly sought after by collectors.
Strap: fitted with a generic "Speidel" brown leather strap and buckle, which attached to the watch measures approximately 205 mm from buckle tip to last hole.
