Authentication
A mechanical alarm is expensive to build and almost never faked. If the alarm actually rings on time and the reserve disc at 3 responds, most questions are already answered.
Known issues in the market
- The Advisor is the only Tudor with this complication, and it ran for a limited period. Watches described loosely as a "Tudor alarm" without the reference are worth pinning down.
- The alarm has its own mainspring barrel and its own winding. A watch whose alarm will not sound after being wound is a service issue rather than a quirk, and on this module service is not cheap.
- Case construction is titanium middle with steel bezel and back. A listing describing it as all-steel or all-titanium has it wrong either way.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| dial | Alarm on/off aperture at 9 | A window that visibly changes state when the pusher at 8 is operated | A printed marker that never changes, or an aperture that sticks between states |
| dial | Alarm power-reserve disc at 3 | A disc that climbs as the alarm barrel is wound and falls after the alarm sounds. It is independent of the main going train | A disc that tracks the main power reserve, or one that does not move at all |
| movement | Alarm function under test | Set, armed and left to run, the alarm rings at the set time with a clear mechanical buzz against the caseback | Silence, or a faint sound suggesting the hammer is not reaching the gong |
| case | Case materials and pusher | 42mm, titanium case middle against a steel bezel and caseback, with the distinctively shaped alarm pusher at 8 and 100m water resistance | A uniform case colour throughout, or a plain round pusher |
Common legitimate replacements
- Straps and bracelets are consumables; Tudor supplied this reference on both, so either can be original.
- The alarm module is Tudor-specific work. Ask who serviced it rather than only when, because a general watchmaker may not have touched the alarm train at all.
Expert resources: Monochrome, aBlogtoWatch and SJX all published hands-on coverage of the Heritage Advisor with the specification block and clear photographs of the alarm indications. Tudor’s own site keeps a tutorial on operating a watch alarm.
