Rone Vintage Triple Calendar (Chrome-Plated Case, Swiss Made) – Unusual 1940s Collector’s Watch From watchmaker private collection! Model Overview This vintage Rone combines a striking calendar display with the restrained proportions of a mid-century Swiss wristwatch. A window beneath 12 o’clock shows the month, while two concentric scales around the dial display the days of the week and dates from 1 to 31. Separate crowns at approximately 2 and 9 o’clock give the watch its distinctive profile. The small seconds register sits above 6 o’clock, and the dial is signed Rone, Non-Magnetic and Swiss Made. Its layered calendar layout and visibly aged dial make it a characterful piece for a collector of unusual complications. Technical Specifications Detail Description Brand Rone Model Vintage triple-calendar wristwatch Movement Swiss manual-wind mechanical movement; calibre - clean and serviced Production era Approximately 1940s–1950s; exact year unconfirmed Case Chrome-plated case with stainless-steel back Case size Not measured Crystal Type not confirmed Water resistance Not tested; keep away from water Strap Black leather-style strap; originality unconfirmed Case, Dial and Calendar The silver-tone case has long, shaped lugs and two crowns. It shows substantial wear consistent with age, including scratches and areas where the plating has worn through, particularly around the bezel and lugs. The stainless-steel back is marked “Stainless Steel Back / Swiss Made”; an internal case number is also visible in the photographs. The cream dial has bold Arabic numerals, luminous-style central hands, a subsidiary seconds dial and a month aperture at 12 o’clock. The outer calendar tracks are an especially appealing feature: the date scale is numbered 1–31, while the inner track carries weekday abbreviations. “Brevet” appears on the outer ring. The dial has clear, uneven patina, spotting and discolouration. These marks are part of the watch’s present condition and are shown in the close-up photographs. Collector Appeal The attraction here is the display: the month window and two calendar rings give the watch far more visual detail than a conventional time-only piece, while the small seconds and shaped hands retain its period character. It is a good candidate for a collector who values unusual vintage Swiss calendar watches and an honestly aged appearance. Condition Report The watch is offered in vintage, visibly worn condition.
