Ok, here is the deal. I recently received 2 watches:
PAM 184 and GO Senator Navi chrono.
Both are amazing watches.
However, that said, I noticed that PAM was running about 20 sec/day fast and GO was running about 40sec/day slow for few days that I timed them.
Considering both were under warranty, I have decided to stop by near by AD (for both, how convenient) to get the watches regulated under warranty - since I need a watch to wear, I have decided to drop off GO first since it appears to suffer more from deviation.
Now, the watchmaker on the premises happened to be out on the floor and looked at my watch and asked me "What is wrong with it?" and I told him it is running about 40/day slow.
He said "That can't be for a GO!!!" He takes out his timing machine, puts the watch on the timer and what do you get? It get literally 0 second deviation /day solid for literally 5 minutes!!!
He told me "I don't know WHAT you are timing the watch with, but you should throw that out and use that for timing" (I was timing them using time.gov) he also said 'My expectation is set very high with GO, but that tops my expectation".
I said, ok, can you time this one too? I handed him my PAM 184, and he put it on the timer, then I get deviation between -1 to +1/day but overall, it was mostly standing at 0 deviation as well.. I was kinda dumbfounded.
He told me that he will time the GO for 3 more days and will let me know whether i should consider sending it in or not.
Considering that I will be out of watch for several weeks, I don't think given that fact that I would not send it in but has anyone ran into this before? I don't think my timing method is that bad (I set the watch, then send myself an e-mail as reminder of when I set the watch, then check couple of days later) and it was pretty consistent for last 50 watches..
I considered magnetism, but it wouldn't spontaneously de-magnetize them selves in watch store. Granted, it was rather stable experience without watch moving on my arm, but still..
