Aquascaphe TPD & Winder Settings | Swiss Watch Store
The Baltic Aquascaphe is an automatic watch: it winds itself from the motion of your wrist, but on the days it sits unworn a watch winder keeps the mainspring topped up. This model carries reference SB01. It is powered by the Miyota 9039 movement. Below you'll find the exact TPD setting and winding direction the Aquascaphe needs.
TPD and Winding Direction
The correct setting for the Aquascaphe is 800 turns per day, bidirectional: 800 turns per day with the rotor turning in both directions.
| Turns per day (TPD) | 800 |
| Rotation direction | Bidirectional |
| Movement | Miyota 9039 |
Why the Correct Setting Matters
An automatic watch is only as accurate as its power reserve allows. Keep the mainspring properly tensioned and the Aquascaphe 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 Aquascaphe
For the Aquascaphe, look for a programmable winder offering a 800 TPD bidirectional 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.
Aquascaphe Winder FAQs
What's the correct TPD setting for the Aquascaphe?
The Aquascaphe is specified at 800 turns per day. Most programmable winders offer this as a standard preset.
Which winding direction should I use?
Bidirectional — the winder should rotate in both clockwise and anticlockwise directions.
Can I use any watch winder for my Aquascaphe?
Yes — provided it's programmable. Verify the winder offers 800 turns per day with bidirectional rotation before buying; fixed-setting winders may not match.
