Sorry for not chiming in earlier wheaton.
The lug width is indeed 22mm. However you will come across two problems with this strap I think. First and foremost is finding one. I can't imagine too many of these will be floating around but you never know I guess. Second is that it is not a traditional nato strap so mounting it may not be strait forward. The spring bars for the THC are built into the strap (see pic) so I am not sure how well the PO will stay put if it is just threaded through the normal spring bars. Maybe OK but I dunno. Actually now that I think about it that's the same as a normal nato right.
And before you ask......no I won't part with mine
Ztech. Are you trying to outright purchase one or did you sponsor trough kickstarter? I think most of us who have them got them through the startup at kickstarter. My understanding is that they were overwhelmed with the initial run for supporters and are still catching up.
Ofrei has hands in almost any size you need. Especially sweep hands. Hour and minute would be tougher to find a match for given that these normally are unique to the watch.
After wearing it around for a few days my only annoyance is that it always goes to sleep. So you have to wake it up to see the time. Almost as bad as using a cell phone for a time piece. I suppose the battery wouldn't last but a few hours if it was always on but still. For me I probably won't use it as a watch but a handy MP3 player for when I ride my motorcycle.
Given the difference in case dimensions I would think the ring would be different size. The inner diameter would be good to go so worst case is you sand down the outside to fit.
In order of when I took it up starting back in grade school: Trumpet, Tenor Sax, Bass, Drums, Guitar. I think that's it. Only playing the bass and guitars recently.
