Seaforth TPD & Winder Settings | Swiss Watch Store

An automatic like the Halios Seaforth only stays accurate while its mainspring holds charge. It is powered by the ETA 2824-2 movement. Set your winder to the figures below and the Seaforth stays wound, accurate and ready to pick up.

TPD and Winding Direction

The correct setting for the Seaforth is 650 turns per day, bidirectional: 650 turns per day with the rotor turning in both directions.

Turns per day (TPD)	650
Rotation direction	Bidirectional
Movement	ETA 2824-2

Why the Correct Setting Matters

The correct TPD mirrors what your wrist would do naturally across a normal day. It holds the mainspring at a healthy charge so the Seaforth runs at its best and is ready to wear at a moment's notice — exactly what a watch winder is for.

Don't worry if you're unsure — you can't break a modern automatic with the wrong winder setting; the slipping bridle on the mainspring makes overwinding impossible. The right setting just keeps everything running at its best.

Choosing a Watch Winder for the Seaforth

The key feature to shop for is programmability: independent TPD and direction controls that cover 650 TPD bidirectional. Single-watch winders are ideal if the Seaforth flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.

Seaforth Winder FAQs

What's the correct TPD setting for the Seaforth?

The Seaforth is specified at 650 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 Seaforth?

Yes — provided it's programmable. Verify the winder offers 650 turns per day with bidirectional rotation before buying; fixed-setting winders may not match.
