Powering the Twelve

Post by Lesn »

Hi, I’m a new member having just received the Twelve Ti and have to say the watch is even better in the flesh. I have a question about powering the watch and the length of time it should last. How many turns of the crown fully wind the watch up and is it possible to overwind? Currently I have wound it with 30 turns and, unworn it’s powered down after 26 hours. May seem like a silly question but would appreciate some advice. Many thanks

Hello and welcome.

We had a topic recently about the best ways to start and power an automatic.

offtopic/shake-to-wake-or-t62029.html

Even if you give them a few winds to get going it’s better to let them power up on the wrist. I have the same watch and after a few days initial wear I let it run down; it lasted slightly over 55 hours.

Thanks, I ask only because I don’t wear the same watch every day so like to keep them powered. Is it possible to overwind? Appreciate the link

It isn’t really possible to overwind an automatic watch because it has a clutch mechanism that slips when fully wound.

However, there is a kind of accepted wisdom that Sellita movements are a little delicate for daily winding. I must admit I’ve never had a problem with one. My habits are slightly different in that I wear the same watch for several days then put it back in the box. I don’t keep them running if I’m not wearing them, so automatics automatically stay powered up (excuse the pun – but that’s what they were designed for).

@Lesn Welcome and Congratulations on your Twelve Ti :clap:
I'd give it maybe 40 or more turns winds of the crown to get an accurate power reserve.
This has the new Sellita SW300-1 COSC so it might need a few more turns as it should have a 56 hour power reserve.
For example, my C65 Aquitaine has the Sellita SW330-2 with the same power reserve and that takes over 60 turns at least to get full power reserve.

I’d add that the measure of a “turn” when winding is not universal. It can vary from person to person. Do you measure precisely if the crown has turned 360 degrees, or do you count the motion of running the crown through the full length of your thumb as one “turn”?

But hopefully it’s consistent for yourself and for the same watch. So if 30 turns give you 26 hours, do 60 turns give you 52 hours accordingly?

My approach to powering up an automatic watch is much along the lines that Steve uses. When I first started wearing Christopher Ward automatic watches, I followed the manual instructions & gave them about twenty winds to get the movement going. I have found that all that I need to do is wear the watch for a few minutes while I am getting myself around in the morning. Once the watch starts running, I set the proper time. A simple method that works for me & avoids the unintended consequence of accidentally cross threading the crown if it isn’t quite in the correct position. I haven’t had any issues with my watch running down or not keeping time until I decide to take it off & give it a break in my watch box.
