Very unique and fun Tudor 42mm titanium and stainless steel mechanical alarm watch on the original three-link bracelet. Silver dial featuring a date sub-dial, alarm power reserve indicator, and ON/OFF aperture. Clean, modern execution of Tudor's classic 1957 alarm complication. Estimated production circa 2015-2016 based on the J-serial prefix.
Condition: Smooth steel bezel has faint hairline scratches throughout but no deep dings. Sapphire crystal and internal AR coating are completely clean. Case flanks display light surface wear and desk-diving marks consistent with regular use. Bracelet and clasp show typical surface scuffs, primarily on the polished center elements and clasp face. No structural damage or heavy impacts.
Authenticity & Movement Health: Movement is the Tudor Calibre T401 (ETA 2892 base with a proprietary in-house alarm module). Verified for authenticity and performance: • Matching Serials: case serial J47#### matches inner case specifications perfectly. • Beat Rate: Timegrapher confirms the correct 28,800 VPH (4Hz) for this movement. • Performance: Clean trace lines with a rock-solid 0.0ms beat error. Currently tracking at -10 seconds per day amplitude at 264°. • Health: Dial-up testing shows no signs of magnetism; mechanical alarm functions crisp and winds smoothly.
Specs: • Size: 42mm diameter, 14mm thickness, 49.3mm lug-to-lug • Movement: Tudor Calibre T401 automatic with mechanical alarm module • Depth: 100 meters (330 feet) • Power reserve: 42 hours • Includes: Watch only (no box or warranty card included)
