Be honest, your Sub/DS's Glidelock...

[kareemthedream33]

I use it several times a day. Frankly, I find it hard to wear watches without glidelock now!

Rig, no but six upgrades make the case.

I do use the glidelock on my sub as well as the easy link on my GMT, but not often. Yet, I very often wished that i could make micro adjustments on my old 16610 and 16613. My theory for this is that the ceramic model watch heads stay centered on the wrist better than the previous models, and "stay put". Same thing with my Ulysse Nardin Maxi Marine with steel bracelet, which is completely unadjustable other than removing links, and yet it is the most comfortable bracelet.

I never use it.

I personally think so. As others said, though I don't use it daily like I expected to, it did allow me a quick and easy perfect fit. Im also one who's weight fluctuates, has something to do with my proximity to Ring Dings, but anyway...the GL does come in handy for when I do Atkins for month or so and drop 25 lbs.

But, the upgrade to the bracelet and clasp is more than just the quick adjust feature. And, there are other worthy upgrades that I feel make the Sub C a finer watch, worth the premium. The relative merits are of course debatable, but, you have: a nicer clasp/bracelet, significantly better Lume/easier to read dial, super case which personally I prefer, I'm a big guy, even without excess ring ding consumption, 6'8", size 17 feet, so, the older Sub was just a little small on me. The C is the perfect size. Then there's the blue hairspring which purists will say is meaningless. Perhaps it's only as good functionally as the prior top grade nivarox, but it's one of the last parts that wasn't in house, so, by doing the spring in house, the movement becomes virtually 100% in house Rolex, which appeals to me.

Then you have the ceramic bezel. I know the pros and cons, theoretically more durable, but way more costly to replace. There's another feature of the bezel I like. The numbers cannot be scratched off, as they're deeply engraved into the ceramic. From what I gather, these bezels are pretty technologically sophisticated. Aside from the rare Internet story of a chipped bezel, they do seem to be extremely durable and virtually scratch proof. I also personally love the way the bezel reflects light, it gives the watch just a touch of a gem quality absent on aluminum insert watches, I realize that's subjective, and arguably at odds with the purpose of a true tool watch.

Thanks for the thorough response, I currently have a 16610 Sub that I have enjoyed for years and am considering making the upgrade.
My dilemma is between finding a z series SD or a new ceramic sub.

I use mine but not anywhere close to everyday. It's a great feature even if it's only used to get the perfect fit upfront.

I use the glidelock about once every few weeks.

When I feel it getting a bit tight, I flip the clasp & glidelock up, make a fist to expand by wrist a few mm, and the glidelock expands accordingly. Flip everything back down and I'm done in a few seconds with instant relief.

To tighten the watch, I haven't figured out a way to do it except to take the watch off and push the bracelet together with two hands (the gl open of course). At first I thought I could simply open the gl with the watch on my wrist and use free my hand to squeeze the bracelet for a tighter fit, but that doesn't work for me. YMMV.

Overall a great feature. I wish there was less taper in the bracelet, but that's another story.

Had my Sub lv now for less than a week, and I've used the feature multiple times already. At first, I used it to get just the right fit. This took a modest amount of tweaking. I like my watch to be a little loose where it will fall down to the wrist/thumb interface with just a tad of shaking/movement. When I am working, I need the watch to fit more tightly and stay put on my wrist slightly up the arm, so I have been adjusting the watch at least a couple of times a day. The fact that the mechanism is so solid and brilliantly simple makes me want to play/fiddle with it also. I can definitely see this component of the watch being the first thing that I need to have tightened up/repaired, because no matter how well made it is, I can tell I'm going to wear it out! I absolutely love it.

I have the DSSD and use the glidelock to adjust as needed. It is very convenient and the resulting fit is perfect.
