Check the listing for details. Adapter for Casio G-Shock watches to use Leatherman Tread. Condition: New without tags. Listed at 10.00 USD. Here we go again. I have a Casio G-Shock (GBX-100 to be exact). It uses the standard polymer / resin band that has a 16mm lug that inserts into the watch body and secures using a spring pin. On every watch I've used daily over the last few years; I adapt it to my trusty Leatherman Tread wrist band. Unfortunately; I was unable to find a reasonable solution for the G-Shock. Subsequent to this; I designed and made my own; and here it is for sale! What do you get when you purchase from me? Well, you'll get two (2) "tight adapters" which bring the tread close to the body of your watch (see photos). In addition; you'll get one (1) "long adapter" which is like a tight adapter, but adds a tad more length to the band for "in-between" sized wrists (again, see photos). For instance, when I set out prototyping; I intended to make only the short adapters, but prototyped with the long design; not wanting to make it so short, it would not work. After all my iterations; I found that using tight adapters on both the top and bottom of my watch made the band too tight for my liking. I swapped out one of tight adapters with one of the final "long" prototypes; and I found it to fit perfectly with a slightly loose and breezy fit. This made me think....If I sell it to others, they may have the same problem; so I should include one of the long adapters too...just in case. For what it's worth, the "long adapter" adds to the band about the same length as the super stubby "half sized" tool link. So if you really want to use 2 short adapters, you can utilize or remove the stubby link instead. For me, the tool load out I want, made the long adapter the best choice for me; and probably for some others as well. Will it fit your watch? Unfortunately, I only have the one G-Shock watch; so I'm not able to test or try it on other watches. I do know, however; that this lug size (16 mm) is fairly standard and is the most popular size when I google "g-shock replacement band". If you know the smaller protrusion (lug) that installs into your watch measures 16mm; then this should more than likely work for you. If it doesn't; I'm reasonable and accept returns without grilling my customers. If you can give me good photos and measurements, I might even design a custom version for other sized G-shocks! Is this adapter durable? Yes! I've used mine for a while with average day to day dings and crashes into things. It has NOT broken, fallen apart, or showed signs of failure. I printed it in the most durable way possible (best orientation, with 100% (maximum) infill). They are printed in PET which is one of the most durable plastics. It's the same plastic used for soda bottles; and we all know how much abuse they can handle. Honestly, one watch owner to another; I truly feel that these adapters are more than strong enough. I'd wager that the adapters are more durable and could handle more punishment than the stock spring pin (and the plastic holes they snap into) that holds the original bands on. You'd most likely tear your watch apart first, before breaking the adapter. If any one wants to test them and post a video about it; I'd be willing to watch and take notes/advice. Also, if you are hesitant; buy it and try it out. Like I've said; I'm a reasonable person and if it doesn't meet your expectations; I'm always willing to work out a refund. If you insist on only purchasing a metal version; please let me know....and if you can; help me purchase a metal 3D printer! I'd be glad to make it in metal then! How does it install? Well, you first use a super small flat-head screwdriver or "watch pin tool" (about $7 on Amazon) and remove your old band and attachment pins. Then you re-use those same pins to attach the adapters onto your watch. BUT FIRST! Unscrew your Leatherman Tread, and screw the screws into the attachment holes of the adapters. The holes are not threaded and it will be tight to screw into at first; but the screws should easily cut their own threads into the plastic. Why did I make it this way? Simple, I don't know which Tread band you have. There are thread differences between the genuine $340 Leatherman band, and the cheaper $30/$50 Chinese clone bands. If I pre-threaded it for one, it would alienate the others. Just designing them with a slightly small hole, allows everyone to customize their adapters for their bands. It adds about 2 minutes to the process; but I highly recommend you screw your screws into the holes BEFORE installing it onto your watch. Once screwed in, just unscrew it and flip it over to the other side. This will make installation MUCH easier. After pre-threading, install the spring pin (used to hold your old band into the watch) into the hooded hole near the tip of the 16mm lug. Slide the lug into your watch by inserting one end of the spring pin into its receiving hole in your watch. The spring pin will be too long and will prevent the lug from being fully inserted. Use a fingernail, or the aforementioned watch pin tool, to compress your spring pin so that the lug can be fully inserted into your watch. Move the lug around until the spring pin becomes fully captured by the holes in your watch's body. Do this for both sides, and then you'll be able to install your Tread onto the adapters. Size the band by adding or removing links (or swapping out to the "Long Adapter"). Once it fits to your liking, enjoy! Legal notes: What's for sale is my designed and 3D printed adapters. As mentioned earlier, you'll receive 3 adapters (2 short, 1 long) to make sizing easier. You WILL NOT receive a watch, or Leatherman Tread or a knock off band! Only a set of adapters.
