Fifty Fathoms Bathyscaphe 43 TPD & Winder Settings | Swiss Watch Store
Left unworn, the Blancpain Fifty Fathoms Bathyscaphe 43 will run down within a couple of days — a correctly set watch winder stops that happening. This model carries reference 5000. It is powered by the Cal. 1315 movement. Here is the TPD and direction this model calls for.
TPD and Winding Direction
The correct setting for the Fifty Fathoms Bathyscaphe 43 is 955 turns per day, clockwise: 955 turns per day with the rotor turning clockwise.
| Turns per day (TPD) | 955 |
| Rotation direction | Clockwise |
| Movement | Cal. 1315 |
Why the Correct Setting Matters
An automatic watch is only as accurate as its power reserve allows. Keep the mainspring properly tensioned and the Fifty Fathoms Bathyscaphe 43 will hold its rate and be ready to wear the instant you pick it up — no resetting the time and date. Set the TPD too low and the watch can run down between wears. The movement will not be damaged (modern automatics have a slipping mainspring that prevents overwinding), but an under-wound watch is simply not doing its job. Correct settings are about accuracy and readiness, not safety.
Choosing a Watch Winder for the Fifty Fathoms Bathyscaphe 43
For the Fifty Fathoms Bathyscaphe 43, look for a programmable winder offering a 955 TPD clockwise programme. One watch? A single winder. Two or more automatics? A double or triple winder keeps the whole rotation ready. You'll find suitable models in our watch winder collection — check the programme list before you buy.
