[…] Tissot Men’s Heritage Visodate watch uses a form of movement that is called ETA Caliber 2836-2, which is known to be excellent and highly reliable. It usually will only either speed up or slow […]

I am contemplating ordering a Sandoz Submariner TT diver’s day-date watch which uses the 2836-2 partly because of sentimental reasons, a Sandoz was my first long-term brand-new watch back in my high school and college days plus it is relatively scarce on the market.

How long would a Tissot Visodate have to be worn to develop the full power reserve of 40 hours? Will it achieve full power reserve simply by being wound manually?

Hand winding is the most efficient way to add power reserve to your watch. I think Tissot recommends 40 turns….But there is also a built in clutch which prevents harmful overwinding.

Just wondering if this movement can be adjusted easily? Mine is 15 seconds fast per 24 hours

15 seconds fast is nothing imo. I won’t adjust it for that.

I would advise leaving it alone if it is running reliably

Thanks for your replies, it is actually 40 seconds fast per 24 hours, better fast than slow!

The Tissot PR 100 P764 Automatic also uses this caliber. Tried finding out for sure before i purchased the watch but no information was found on the older PR 100 Automatics just the newer PR 100 Models had the Powermatic 80’s and the 2824-2 calibers.

My Fortis Flieger Pro uses this movement. For me, it’s very reliable: -3 seconds per day, with very little variation.
