I decided to try some on today. My perspective is from someone who’s been into watches for a long time but only able to try higher end watches (Nomos, Omega, Stowa) for the last 5 years.
I tried on:
38mm white sport (they didn’t find a black one)
42mm black sport
42mm milanese loop
42mm leather loop
42mm classic buckle.
First up, I really don’t like the look of the black rubber sport band. I like the black sport case, but the matte finish of the band just turns me off. It feels good, yes, but the look is very cheap when you see the strap on the wrist, imo. I think Gruber is on bath salts thinking this material is acceptable luxury for the 10k watch.
Also, the 38mm model feels very small on my 6.5” wrist. it looks like an old 1950s vintage stowa I had which was 33mm in diameter with small lugs. it looks small.
If there are hands on pictures out there that make the 42mm sport model look too big on smaller wrists like mine, I think it’s because the band is not tightened enough. the rubber doesn’t want to bend in and hug the wrist as much as the other straps (it’s stiffer at the case junction) so it bows out and makes the watch look bigger in some pictures than it is.
The leather loop was very comfortable but the feel of the leather was oddly plastic-y and stiff. On one hand, it gives some confidence it won’t fall apart fast, but it’s not a soft feeling leather at all. I didn’t really like this one
milanese loop is very, very thin and feels like fabric, not steel. it’s not a typical, large shark tooth mesh that you get with some dive watches. it’s much more fine and vintage feeling and, dare I say, feminine. One thing that I don’t like about watch straps is when they do not taper along their width - it makes them feel too wide. the milanese loop is straight all along it’s length so it looks very wide along the bottom of the wrist. I doubt many will care but I would have preferred a 2mm taper like with most other bracelets and straps.
the classic buckle was actually my favourite. simple, clean look with some nice details on the buckle. tapered strap. Leather felt sturdy and flexible, but not as luxurious as some more supple leather straps I’ve worn. I liked the feel more than the leather loop. I think if i had to pick one model, it’d be the basic classic buckle.
I did not try the modern buckle because it only comes with the 38mm watch and that model is just way too tiny for my taste. I also did not try the link bracelet as it’s very expensive and I wouldn’t be able to get a sense for fit as they don’t let you take out any links.
