16710/16713 Question

[turbineboy]

GMT II Question.

Based on what I have read, I understand the bezel on the GMT/GMT II is supposed to be bi-directional.
However, if the bezel only turns in one direction (CCW), what could be the most likely reason for this ?
Does this automatically mean I need service on the watch or are certain series of 16713's only uni-directional or could the timepiece be a fake ?

If anyone has come across this issue with their GMT-II, please share how I may resolve this issue or if this is normal for the GMT II (model 16710 or 16713).

TY

Post a pic. It could just be gummed up.

Is it possible perhaps someone install the tiny spring clip from a Sub to the GMT?

Dirty or the spring is broken. Let someone pull off the bezel and you will see what happend.

Can you dive with it then?

Pulling off the bezel...is that something I could attempt by myself and if so, what should I do or once it's off, does it go back on easily. How would I be able to tell if something is broken ?

Also, the bezel clicks twice for every second on the dial when I turn. Are they supposed to click once for each second marker or twice for each second marker ?

Thanks for your help.

the bezel has no interaction with the movement, so, no, a bezel that only rotates one direction does not mean that a watch needs a service..

the only difference in the one direction and the two direction bezel is a wire "spring" that presses against the bezel teeth at an angle. As you turn the bezel in one direction the teeth click over the teeth. If you turn it the other direction, the angled wire digs into the teeth keeping it from moving in one direction...

The GMT has a bend at the end of the wire, so it never digs into the teeth in either direction.. If the bend wears through and breaks off, you have a sharp end then, and it functions like the one direction wire...

Here you can see the wire with a sharp end... The GMT has a bend at that end..

thanks.
So how many clicks should I hear when I turn the bezel - one click for each second or 2 or more ?

And how would I remove the bezel to check this ? Is it something that can just be wedged out with a flatheat or do I need special tools for this ?
Would you recommend a novice attempt this or is this better left to a watchmaker ?

I use a butter knife with the tip wrapped in masking tape. Very high tech, I know. It's a little unnerving at first, but really pretty easy. There are a few "how to" writeups and videos floating around this site as well.

This is not a good idea for a novice since you still wouldn't know how to repair and re-install.

But just my opinion. If you get stumped, or break something you can always send it to a qualified watchmaker afterward.

Older bezels are 120 clicks around the dial.. .. It's not rocket science to take off and replace a bezel if you are handy with your hands..

We have a DIY in the Reference Library for changing an insert and takes you step by step through removing the bezel...

120 clicks on my 16710 when rotated 360deg. I find that my bezel turns much more smoothly counter clockwise than it does clockwise.

Thank you for the answers. I think I will prefer to have the bezel checked out by my local watchmaker. I may be handy with tools, but this is something I would rather not risk :)
While it is being checked for the bezel, may have him change out the insert as well - has been scratched up a bit with daily wear.

I looked thru the reference forums - found a ton of very good information there, but nothing on a DIY bezel cleaning/replacement. So if anyone finds this thread, please post link to same.

Thanks again for the great info.

I came across a very minty GMT pepsi bezel today for a very nice price. Can't quite understand why I am drawn to the GMT's so much. If the owner doesn't sell it quick, I may have to go after my 4th GMT pretty soon.
