Sicura Sub Diver – Automatic – Rare, with Original Signed Jubilee Bracelet – 1970s In very nice condition, with minor signs of use and hairline scratches. Its 25-jewel automatic movement works perfectly and keeps accurate time, with a daily accuracy within 30 seconds, a measured amplitude of 245–257°, and a beat error of 0.5–0.6 ms. Flawless, original, unrestored black dial with luminous hour markers and hands. The hour markers still glow nicely after exposure to strong light, while the luminous material on the hands glows more faintly. Silver-tone central seconds hand with an arrowhead-shaped tip. Date window at 3 o'clock, with the date changing perfectly around midnight. Original, unrestored, bidirectional rotating bezel in exceptionally nice condition, with two minor signs of use: a small pinpoint mark on the silver-tone edge above the 50-minute marker, and a slight indentation, presumably caused by a previous impact, on the silver-tone section just before the 20-minute marker. The bezel's black paint and the silver-tone markings on the black sections are flawless, sharp, clean, and free from damage or wear. Chrome-plated case with light signs of use – hairline scratches and minor surface wear, mainly along the edges on the caseback side. Very nice signed stainless steel caseback, with one or two more noticeable hairline scratches. A particularly special feature of this watch is its original, factory-signed, Jubilee-style stainless steel bracelet, which is exceptionally rare to find! Among the examples currently available for sale that I have been able to locate, not a single one is offered with the same original, factory-signed Jubilee bracelet. Acrylic crystal free from hairline scratches.
