Micro adjust on the fly - really necessary ?

I have only one of these. I wonder if it's more down to the type of bracelet?

Some are more flexible than others, mesh, beads of rice, so they can better match the contours of the wrist.

I've seen comments before moaning about the slack between bracelet links, but relating to my previous comment, that's a potential bonus.

I like it because of the smaller increments and generally leave it once it’s good. I do make one click adjustments here and there because I can. So it’s nice to have and I miss it on those without.

Never had a bracelet with tool-less micro adjust, and it keeps me from bracelets as a whole at this point, except on very rare occasion. My wrist can easily add a quarter inch of circumference when my forearms are working or it's very hot out. Sizing for that makes my bracelets too loose otherwise, and the watch slides over the distal ulnar head, gets stuck there, and causes pain and reduced range of motion of my wrist when I'm working on stuff with my hands. Bracelets are a no-go for me any time I might have to work on anything, which means virtually always. I need something I can adjust in a moment to keep it on the forearm at all times without being constricting.

I need a micro adjust for a bracelet otherwise I’m using straps. I’m constantly moving up and down sizes throughout the day.

Fit & forget for me too.

Once sorted ,that's fine forevermore - maybe a slight preference for bracelet over NATO because I'm always on the same hole on straps and they get worn out.

I find it hard to believe that your wrist size never changes. Mine fluctuates quite a bit. Much slimmer when it is cold outside and there is no humidity. When it is hot and/or humid, the wrist swells. This is also well-known to happen with fingers. For instance, it can be hard to take off a ring on a hot, humid, summer day.

I have an IWC Ingenieur with an amazing push button micro-adjust system that you can operate with one hand without taking off the watch. Whenever I wear the watch, I find myself adjusting it multiple times throughout the day as I go in and out of buildings or even as indoor air conditioning or heating kicks on. Once you have a micro-adjust system like this, you realize how amazing it is, and it's hard to go back to putting up with a less than ideal fit.

For comparison, I also have the Tudor Ranger with the T-fit clasp and it is nowhere near as good as the IWC. You have to take the watch off to make adjustments, and I needed to buy a half-link to even make the micro-adjust system work. With the IWC, I was able to size the bracelet perfectly so that I was right in the middle of the micro-adjust under normal conditions, allowing me to go tighter or looser as needed. Not so with the Ranger. Of course, the IWC bracelet is also way more comfortable so that is nice too.

In any event, different strokes for different folks. For my wrist, I need micro-adjust if I am ever going to buy a watch with a bracelet again, and I am also picky about it. Fortunately, I generally prefer straps.

So you see how we are all build differently :-) Indeed my wrist size never changes regardless the circumstances.

I totally agree on the IWC clasp...I have that same clasp system on my Mark XVIII and Pilot as on your Ingenieur....it´s better than the Omega micro adjust or Rolex glidelock on my Sub.....but I have no need in using it....guess I am just lucky with never changing wrists.

I feel like if you’re buying a new thing to wear and its a couple thousand bucks it should be comfortable. The technology is there. Just a matter of implementing it tastefully.

The new heavier Rolex bracelets need them on all models, but I don’t miss them on the old ones which are lighter and more comfortable and can be worn looser.

I have a San Martin I use at work and it's very useful

It really makes a huge difference to me. Everyone's body acts a little difference, so it's not always as big a deal. But I heavily favor Glashütte Original, IWC, Moser, Rolex, San Martin (odd company, I know), and all those microbrands that offer on-the-fly adjustment mechanisms because of that.

Those that don't, like Zenith, Omega, and Grand Seiko, suffer by comparison. That doesn't make them unwearable on a bracelet, but it depends on the model.

My wrist size can change close to half an inch during the summer months.

My bracelet will start out loose enough to almost spin the watch head around my wrist and by the afternoon it feels like a constrictor.

Yes you are one of the lucky ones.

Incredibly useful and appreciated.

I've had a need for them! I'm very picky about how my watch fits, and thankfully I can get all my watches on bracelets to fit perfectly. With some of them though, they get too tight when I go to warmer countries or when I exercise. In those cases the small adjustments are awesome.

My favourite ones I have are the Mido Ocean Star Tribute and the Rolex Oyster Perpetual.

The wrist change I have through the day is one of the reasons I often (80% of the time ) opt for a nato or fkm strap

As a very active person running around mountains and lakes etc… the micro adjust is really useful as I’m adjusting multiple times a day depending on what’s happening.

It’s part of the reason why I have Erika’s MN straps for most of my watches as they’re easy to adjust for a perfect fit

On the fly micro adjust is a feature and as such it may have benefits for some and none for others. Good marketing will convince us that it's a feature with huge benefits for everyone and that none of us knew how much we suffered before it was made available (for a moderate price of course) to us.

My wrist can swell by a lot throughout the day, especially at this time of year where its very hot during the day but very cold at night. Watch can go anywhere from snug to very loose.

Not a bracelet fan but for the one watch I do have on a bracelet I do wish it had micro adjust

I definitely prefer on the wrist adjustable bracelets.

Yes for me, my wrist size changes many times a day, from wake-up to night. Depends on the weather, temperature and activity.

I have a bracelet and I seldom use it, never in fact, because of that and because it lacks adjustment on the fly.

I am considering to purchase a Bonklip bracelet, but so far I am happy with straps (leather, rubber and elastic).

I have a few micro adjustable bracelets including one of the best on my Submariner. I never use them. I just wear a watch a couple of mm further up or down my wrist depending on how warm or cold it is.

Yes!! 100% critical

No it’s not. I’ve done it. Comfort is everything

It’s honestly really nice to have in the summer and it just helps to get that perfect fit and requires minimal effort to get it. Considering many micro brands that make watches for under 1500 or 1000 dollars have it there is no excuse for more expensive watches to avoid that feature imo.

Kind of like heated seats in a car. You don’t need them, but once you have them, it is hard to imagine not having it.

I never used to like bracelets and could never get the fit right for the ones I had. For this reason, I was very strongly in the camp of “my next watch needs to have micro adjust”. However, the last watch I bought was on a bracelet and had no micro adjust, but the fit is excellent, so I love it on the bracelet. My wrist size doesn’t seem to change very much. Although I’d still be curious about having one with micro adjust, I think it’s not a deal breaker.

I enjoy a well engineered, and a well designed, micro adjust bracelet is part of that. At least as useful as a tacymeter scale.

But after fiddling around yo get the right fit, I dont touch it

I change my adjustments fairly often. I seem to always be in a slight weight flux. Tool-less is great but I don’t mind using a tool of the rest of the watch is great. My Uncle Strap bracelet on my Seiko wears great but every now and then I gotta adjust with a tool. No problem.

It’s the butterfly clasps that get to be a pain. Adding and removing links is a pain and goes from too big to too small every time.

it has become a no go for me. Between temperature fluctuations in New England throughout the day and getting older so sodium levels in my food can cause wrist swelling, and being a drummer when i am practicing more often my wrist stays bigger.

I'm at the point in my collection that when i am looking to spend $1000 or more on a watch with a bracelet, if it doesn't have on the fly adjust, I'm passing on it.

yes, it is important. Depending on your physiology, your wrist can swell/contract 10% or more in response to temps and time of day. I especially love the IWC/Glashutte/Lange system with the button on the clasp.

I think it should be standard!
