Width: Approximately 34.5mm Length: Approximately 41mm Thickness: Approximately 13mm Lug width: 18mm This is a mechanical alarm watch that gained attention with the catchphrase "The watch that rings a bell." It's a popular collection manufactured for only 10 years, starting in 1958. This item is a rare 1st model that had a short production run! It features upright indexes and gold dolphin hands. Unlike the second model "4H," it employs a rotating disc alarm hand, reminiscent of a certain Memovox design. The 14KGF gold-filled case has a heavy round form, and the back cover is a SS snap-back with holes to amplify the alarm sound, acting as a resonance lid. This is a masterpiece that allows you to enjoy the deep, mechanical "g" sound and the vibration felt on your wrist, which are not found in modern alarm sounds. ・We may cancel bids from those who feel uneasy about the transaction. ・There may be unseen stains, discoloration, dullness, scratches, and scuffs in the images.
