Black Bay 41 TPD & Winder Settings | Swiss Watch Store

A watch winder only does its job properly when it is programmed to match the watch. For the Tudor Black Bay 41 (reference M79540, powered by the MT5602), that means dialling in the right number of turns per day and the correct rotation direction — both listed below.

TPD and winding direction for the Black Bay 41

The Black Bay 41 needs 650 turns per day (TPD), winding bidirectional (rotating in both directions). Programme these exact figures into your winder and the mainspring will stay optimally tensioned.

Why the correct setting matters

Why bother getting the numbers exactly right? Because a correctly set winder means your Black Bay 41 is always charged and keeping good time, straight from the box to your wrist. Too few turns and the reserve drains; the watch stops and you are resetting everything. Modern movements are protected by a slipping mainspring, so there is no risk of harm from a wrong setting — but precision here is what separates a well-kept watch from a neglected one.

Choosing a watch winder for the Black Bay 41

Invest in a programmable winder that can be set to 650 TPD bidirectional — fixed-setting winders are a gamble for specific calibres. A single winder is perfect for a one-watch collection; go multi-watch if you rotate between several automatics. Browse the full watch winder collection to find yours.
