Dial Design and Hands
The dial displays a two-tone silver and champagne layout with a diamond-patterned textured surface on the central section and outer edge. The cardinal hours (12, 3, 6, and 9) feature silver-tone Arabic numerals, accompanied by silver arrow markers with luminous dots at the remaining positions, and light-black baton minute marks. Time is displayed using silver-tone Dauphine hour and minute hands filled with luminescent material and a red sweep center seconds hand. The dial is signed 'GRUEN PRECISION' below the 12 o'clock position and 'AUTOWIND' above the 6 o'clock position, with light surface patina noted by the seller.
Movement Details and Dating Caveats
According to the dealer's movement transcription, the watch is powered by a bumper automatic Swiss caliber 462ss marked 'Autowind Veri-Thin Patented Gruen Watch Co. Precision Switzerland Seventeen 17 Jewels Unadjusted IM47778 462ss'. As the case back is not opened in the available imagery, these caliber designations and movement serial numbers are documented solely from the seller's text. The seller dates the piece to 1954 and claims Gruen started producing bumper automatics in 1947. However, the listing provides no official factory records or archive documentation to independently corroborate this specific year of manufacture.
Case Construction and Exterior Dimensions
The watch is housed in a round case with faceted lugs, described by the seller as stainless steel. Recorded measurements from the listing include a case diameter of 31.3 mm (34.2 mm with crown), a lug-to-lug length of 38.3 mm, a thickness of 11.3 mm, and a lug width of 16.1 mm. It is fitted with an aftermarket 16 mm black genuine leather two-piece strap with a silver-toned buckle. Internal and caseback stampings transcribed by the seller read 'Gruen Automatic Water and Shock Resistant Anti-Magnetic 24401F Guildite Gruen Watch Co. Switzerland 462ss'. These interior marks and alloy stamps are not directly visible in the single exterior photograph and rely on the dealer's transcription.
