The 39 Formex tapers to 18mm also. Nice to know that both the 21mm for zulu 39 and 22mm for zulu 42 both tapers to 18, that means there is no chance that I would get the wrong clasp when ordering and that I can also ask to try out my artem on their Longines clasp.

I found out that the artem loopless is 7mm between holes, so its kind of inbetween, I find that hilarious, nothing ever seems to want to truly fit togheter between brands.

Hi again, do you know the distance between holes on the artem strap? I just found out the teeth of the Longines micro adjust are smaller but it got a distance of 6.5mm instead of 7.5mm like the Formex, so if the length between holes are closer to longines it may just fit perfeftly without widening the holes and give a complete OEM look to my zulu time, even though it costs x2.

Just checked their site, the 18mm is 7,5mm apart. The perfect combo would be longines smaller tooth with Formexs length. Do you know if both the 42mm zulu and 39mm zulu taper down to 18mm? May go to the mall and check if the longines clasp align with it, but they only got 42mm one on display.

Btw: you have been so extremely helpfull, you are such a nice individual, even taking pics:)! It helps so much.

Thank you so much for checking:)! Now I know Longines length so I can contact Formex to ask what their 18mm is. Want to fit it to my Artem Loopless and have seen people done so. If there is indeed a 1mm difference, and the Formex fits the artem, I think I have to go that route, but hopefully the Longines may fit if the 18mm Formex is also 6.5:)

Edit: the teeth on the Formex seems to be bigger, is that the case? Since people say that the only problem to get the Formex to fit is to widen the holes a little, with Longines I may not have to do that.

Oh Thanks, but I meant are the teeth the same distance from each other on both the Formex and Longines?

Because I know the Formex fits the artem strap and the distance of its holes from each other, so of the teeth on the Longines are the same length apart they will fit over both holes perfectly:)

Hi, I think you answered it but just to be safe. I actually bought a green artem loopless with the omega style clasp for my Zulu Time 39, and its beautiful, the Formex less so, the Longines one is beautiful though and probably a borrowed patent from Formex themselves.

My question is, are the two teeth identical in distance on the Formex and Longines? If so I may get the Longines clasp even though its x2 the price, just looks nicer, and not Formex printed twice + their logo and the push buttons being black..

This is a constant battle for me, the only watch that fits perfect even though my wrist fluctuates a lot is my Breitling SOHII both on mesh and artem loopless. Funny thing is I bought artem loopless for my zulu time 39 also, but my perfect fit there is right inbetween holes, drives me nuts, conteplating buying a Formex Micro adjust clasp or Longines Micro adjust clasp that they have borrowed from Formex but with nicer design and Longines logo but its x2 the price.

I have a pin in my pocket for the bracelet but its comfy 80% of the time thankfully.

The last watch, which is my damn «workplace» watch, the Carrera 39mm three hander have no adjustment on the bracelet, the bracelet is beautiful though, I thought 21mm on the zulu was annoying but this watch is 20.5mm, its the only watch I feel is made for «only» the bracelet though.
