Winder question

Have a seamaster 300 heritage (caliber 8912). Sometimes can’t wear watch for a couple of days due to nature of my job so i have wolf winder.

Clarification questions : 1.) omega site says 8912 needs 720 tbd bidirectional , does that mean prefer bidirectional winding vs can by winded either way unidirectionally without issues? For example: is it better to set the winder to 720 unidirectional vs 360 bidirectional or does it not matter .

2nd clarifying question my understanding is when omega states it needs 720 tbd bidirectional its 720 turns total per day in either way , all clockwise or all counterclockwise or mixed…. not that it needs 1440 total turns per day …Is that correct?

3rd question…my wolf heritage winder only does 900 preset tbd. Anyone have one of these and have an omega that requires fewer tbd. Any strategies for setting this winder daily so it doesn’t wear out parts unnecessarily

I know this has been discussed previously but I’ve seen conflicting responses . much appreciated

Winder? Why ? When you start to wear it one day, just wind by hand 30 X and wear it and be happy. Why use a winder unless you are a Watchmaker and want to test something ?

A couple of days is basically 48hrs. The watch has a longer power reserve than that. 60hrs of power reserve if I'm not mistaken. And 60hrs is a long time. So I'm sure you can put it on again on your days off without the need of unscrewing the crown to wind it and set the time. But then again, that's basically the best part of handling mechanical watches 👍

Is it fine to just set my winder to maximum TPD to keep the power reserve topped up, or is the recommended TPD as per Omega the best route to go even though TPD is much lower?

Depends on the winder model. A Heritage (which I believe you have if it only does 900 TPD) does just that, EXCEPT if set it on bi-directional, where it does that much in each direction. The later models (2.7 and 4.1) fixed that particular foible.

As far as bi-directional vs single, when you turn one way, one reverser locks up and the other spins. Opposite in the other direction. You won't cause any uneven wear unless you set it to the same single direction for a long period (months or years).

I suspect that 725 TPD is enough to keep it at the current level but no more. Don't have anything to back that up but it sounds about right, compared to other watches.

If you had a later model, you could experiment and see just how much it takes. Try a value and leave it alone for a week or so. If it's still running, test the reserve. Reduce the TPD until it stops or loses a bunch of time (meaning it stopped between winding periods). Assuming you have done this for a week or more (for a given setting), you can bracket the amount you really need.

I did this with my wife's Lady Datejust and found 350 TPD is enough.

I love the ability to park a specific watch in the winder and have it ready to go any time.

I put my winder on a timer and set it for continuous run. Then, set the timer to run in cycles of X min every hour to limit it to the recommended TPD.
