GMT running slow?
Just had my 16710 U series Pepsi serviced by RSC Dallas and throught I'd check the time off my I phone, the same phone I used to set it when I got it back.
Well it was almost 14 seconds slow after six months, have only changed the 12 hour hand for different time zones and the date and have not touched the minute or second hand. I think the problem is the I phone is running fast not the GMT slow, maybe the I phone needs a service. |

Wow, that's over 2 seconds a month.

If you rest the watch dial-up at night once in a while it might keep it even more accurate. Try it overnight and check the time the next morning. Most of these watches, particularly the older movements, show variance between positions, usually fast with dial up, slow with crown down, and even slower with crown up. My old 1675 GMT tends to run a tad slow on my wrist, but if I rest it dial up overnight it stays very close, currently showing three seconds fast after two months. In its present state one or two nights resting dial up, or in my case just wearing it at night for few days, will put it back to near zero variance. Of course it's important to have a good internal (basic) regulation done by a watchmaker, then fine-tune it with self-regulation.

My Sub-C is running about 1 sec slow / day. I put it to bed dial up every night. Not sure but it seems a lot of Sub-C owners here run a little slow. Suggestions? Comments?

After reading a recent thread where our own Vanessa mentioned she stored her watch dial down because the crystal is the most scratch resistant part of the watch, I set the watch and put it to bed in the sock drawer dial down (on a cleaning cloth). 24 hours later it was 0.5 seconds fast. I continued storing it that way and it has been consistent - a half second/day fast. So now I simply store it dial down and maybe once a week store it on it's side overnight to give back a couple of seconds when needed. My watch is keeping excellent time. Just checked it now and after a couple of weeks it's dead-bang in synch with time.gov. So try dial down and see what happens. Your watch is keeping really good time, so if you can find one position where it speeds up even a little then you could self-regulate. Hope this works for you.

Interesting. Dial up has done nothing. So... Will be interesting to store dial down to see if it changes anything.

I keep mine on a winder when I'm not wearing it for at least a couple of days. My Y-series GMT-II runs about 5 minutes per month fast. It's never been serviced in the 10-12 years I've had it (bought it new). I just reset it when it gets to the 5 minutes fast mark and don't really worry about it.

Please report back. I'd be interested to know if dial down has an effect on the Sub's movement.

Yeah. My new Hulk which was bought this past April runs a little slow. Loses about a minute every 3 or 4 weeks. My Bluesy which was bought new 17 years ago always ran fast and I used to have to set it back about a minute every 4 weeks. Looks like Rolex is not setting up the movements to run on the fast side anymore. Both watches sit crystal side upwards in a winder when not worn. Actually about a 45 degree angle.
