I've had my BLNR for 1 1/2 years and wear it 24/7. The variance and accuracy have been amazing, generally in the +1 to +2 SPD range. I sent in my watch to the RSC several months ago to get my cyclops/crystal replaced. It came back and immediately was at +5 SPD but after several days started slowing and after a little more than a week had settled into a +1 SPD range. All good.

Over a month later one afternoon it started to take off like a rocket:

I decided to reset the time and my watch tracker app and sure enough it has now locked in at +7 SPD for the past couple of days:

The bad news is it has sped up for no particular reason. I guess the good news is the variance remains amazingly stable. In fact it now seems to have less variance than when the avg. SPD was hanging around +1.

I'll probably "let it ride" for a few weeks to see if it self-corrects but at some point I guess I need to take it in to the AD to be regulated.

Anyone seen anything like this before? FYI, I have a anti-magnetic/degauzer machine and it appears to have made no impact.

Maybe it took a hard knock in shipment? Seems like for a crystal replacement job they would leave the back of the watch on.

I need to correct myself... it actually has been only about 3 1/2 weeks since the watch's return and had been locked in at +1 SPD for about 2 weeks... But still, that seems to be a fair amount of time to associate what's happening now with the service from mid-July.

I'm not sure how a crystal gets replaced?

I know it can be done from the front, but I don't know how Rolex does it.

When you reset the time did you give it a full wind? That could help.

Also, I'm not sure what kind of knock would be a hard knock. The watch was foam packed going and coming. Over the last year my watch has been through everything, has played many rounds of golf, chopped down trees, etc... never an issue. The day it sped up my day was quite docile.

Yup, I've tried giving it a full wind a couple of times now, with no impact. Historically I've never wound my watch and it would just keep chugging along.

wrightbrain · 19 August 2015, 04:50 AM

I've had days where mine will add 7 seconds out of no where, but it didn't keep going that way. I always assume I hit it on a door knob or something throughout the day.

If it was fully wound and was stable for a couple of weeks after return from the crystal replacement, then changed rate about 2 weeks after return and is now stable again but at a faster rate, I doubt the rate change was related to the crystal change. Probably something happened at the 2 week point. You already checked if it had been magnetized. And you don't recall if a hard knock had been suffered. I don't know what else could have shifted the rate so suddenly.

By the way, how do you like that Watch Tracker IOS app?
Pros? Cons?

The watch tracker app is addictive, and very good. Every time I reset the time I begin a new tracking set. I more or less have tracked my watch's time since the day I got it, so knew my movement pretty intimately until this happened.

It provides Offsets, Rates and Variance.

Is this app still in the Apple Store? I can't find it and would like to d/l to track my GMT.
I think it's running around +2 presently. Cheers

Try Googling it.

The App Store search didn't show it at all:
