Hi gigatron, if you look areound you will find some posts by ziggy, the resident expert, they are realy worth reading.
Firstly you should not need to wind a 2836 or any auto for that matter, the wrist movement alown should wind it just fine, winding may damage the ratchet that allows the rotor to wind the watch. Secondly an error of 10 sec a day is not to bad realy, Do you ware the watch all the time or just here and there, the running of the watch depends on what you do when wearing it, active or not. Also the possition that it sitas in when not being worn, it may gain if laid dial up and loose if laid dial down or vice versa also crown up/down ect.
I keep my autos on a winder when i am not wearing them so that they are always at just about the right time and fully wound. try wearing you watch for a full week, set the time first by an atomic clock from the internet and then see if you gain or loose over a week of normal wearing, then you might want to adjust it accoring to that.
Atomic time
I would just give it gentle rocking movement with my wrist to get it going and then wear it.
