Can someone help me to understand on how to measure the accuracy of a watch ? And what is the accuracy scale ? How many sec's loss or gain is considered to be best ?

3 yrs old PR50 quartz
+ca 1 s per 6 months with regular wearing (12h on wrist on average). Excellent model :) I'm very satisfied with it.
3 weeks old PRC200 chrono, seems to run about +1.5s per week.
hi, im new here... have my only tissot pr 516 for 3 years its running +5 sec. per day very satisfied even its not cosc
thanks for viewing![]()
I got my LeLocle with power reserved (T006.424.16.053.00) 3 days ago and it gained 3s/day so far. But little bit confused because at the back it says 21 jewels and on their brochure It says their 25 jewels. Does it because of the movement the watch used? Do anybody on these forul has the same experience? What's the best movement for this kind of watch model.
Tissot PRC200 chrono, 2 years old
+1 to +2 sec/month
Tissot Le Locle (T41142333)
-2 to -3 sec/day out of the box (picked it up yesterday)
Will post here again in three months, once the Le Locle has settled down.

I'm wearing Tissot PRS516 auto non-chrono, i synchronized it with the watches on top and
it runs -1 sec. not -1 sec per day but just 1 second, not more not less and it's a few days now. is this normal because i read different from previous threads
okay, now its +10 late for this month
