I think my watch repair guy did pretty good: -7.6 seconds a day
Of course, it depends upon the accuracy of the Kello app that I use on my iPhone to determine frequency and accuracy, but my 48 year old Benrus is now running only 7.6 seconds a day slow. That's what, a minute a week? I think that is pretty decent for something as old as me{The app seems roughly accurate. I noticed that my Gruen was losing minutes every hour. Kello confirmed that in fact it was almost 4 minutes slow and hour and I used it to adjust the timing. It now gaining roughly a minute a day}

New strap for the Diver.
Got this from a friend of mine. It's a custom Simona that he had made for a Diver he used to have. Thoughts?

demagnitizing on a i-phone
hi there.my constellation automatic came back from the shop (after having the crown re attached to the watch) running real fast - almost 1 minute per hour.i laid the watch on my friends i-phone (in the compass mode) to see if the watch is magnitized.at first nothing happened but after about 15 seconds the compass turned 90 degrees.since then the watch is running perfectly!I only wanted to check the watch for magnitized but its seem to be that the i-phone fixed the problem.anybody seen this happen before?thanks.

SubC hacking question
I have not been able to find any topics on that and I know this might be a stupid question buy could some one smarter than me tell me if the following action damages my movement?When I pull the crown out on my 114060 to set the time I usually try to hack it at 12:00. But from time to time when I pull the crown out, it hacks at 11:58 for instance. What I do is I give it a l gentle push back in just a bit till tension to get the second hand moving again (not all the way till click) just to adjust those 2 seconds and let it go at 12:00. Does that do any harm to a movement or is it ¡±allowed¡± to do it like that?
