Hi All,

Thank in advance for your patience as I navigate my way through my first mechanical watch. So I've had the Sumo Hulk for about 3 weeks now and I'm really liking it. It is advertised as having -15 to +25 SPD accuracy (6R35). I'm checking it and it seems to be averaging +12 SPD. This is in spec, so I guess I should be satisfied with it but how do I "self-regulate" this and maybe tighten it up a little? I wear it at least 10 hours per day as my daily for now. I've hacked it a couple times to turn it back every 4 days or so, but this is probably not ideal. I can remember reading somewhere that regular winding at a consistent time (e.g., 7:00 AM) each day may help. Is this the case? Maybe the watch is breaking in? What's the best thing to do?

Thanks!

Welcome to the forum!!! I have heard of a "break in" period on some pieces but I'm not sure about this one. As far as regulating it I think the only way to do that is to open it up and adjust it. Also the watch may keep better/worse time depending on what position it is stored. For me if it is even close to time I say leave well enough alone as every time we open a watch there is chance of messing ti up. That's just my $.02
 
The name escapes me. But the lever pointed at the plus and minus is used to slow and speed up a mechanical watch. I would suggest not messing with it until you learn to tinker on watches. It’s a very touchy delicate process to adjust it.

A timegrapher would be ideal to have if you really want to regulate the watch as close to zero as possible. But it will always run a little fast and a little slow all the time.

Thank you guspech750! To be honest, I'd rather it be fast than slow. I've always set my watches a couple minutes ahead as it helps me manage my hectic meeting schedule at work. It's always good to know coming out of the bathroom (when I get a chance to go) that I got 2 more minutes to get to that meeting! I also subscribe to the axiom: "You're either 5 minutes early or you're late" - But I don't want to set my watch that fast!

Cheers!
