This is the modern reimagining of Tudor’s 1957 classic alarm watch. Combining a titanium and steel 42mm case for lightweight comfort with a highly technical mechanical alarm, this is one of the most underrated complications in Tudor's catalog. Based on the serial and clasp code, this is an approx. 2015-2018 production year. Mounted on the original Tudor steel/titanium bracelet.
Condition: • Bezel: Excellent shape with only minor hairlines consistent with careful wear. • Crystal: Original sapphire crystal. There is a very, very small nick in the glass at the 4 o'clock edge. It is difficult to see at most angles and does not affect structural integrity. • Case/Bracelet: Very good shape. No deep gouges or significant dings. • Functions: The mechanical alarm functions perfectly—crisp, loud, and clears easily with the pusher at 8 o’clock.
Authenticity & Movement Health: Movement is the Tudor Calibre T401 (ETA 2892 base with an in-house alarm module). Verified for authenticity and performance: • Beat Rate: Timegrapher confirms a healthy 28,800 VPH (4Hz). •Amplitude: Excellent power delivery at 289°, indicating the mainspring and lubrication are in great condition with no immediate service needs. • Performance: Trace is exceptionally clean and straight. Beat error is a near-perfect 0.2ms, indicating a very healthy balance. • Health: The watch is currently running at -6s/d, well within daily wear standards. No signs of magnetism.
Specs: • Size: 42mm diameter | 22mm lug width. • Movement: Tudor T401 (Mechanical Alarm, Date, Power Reserve Indicator). • Depth: 100m (330 feet). • Power reserve: ~42 hours. • Includes: Watch only.
