This is essential that you understand that Watch Brothers take no responsibility if you damage your ring watch or adapter, whilst undertaking the swap over.
You will need to source a very small 1.0mm or 1.2mm Philips screwdriver. Without the correct screwdriver, you may damage either your ring watch or the adapter.
We are working to find a supplier, and hope to be able to offer that as part of a kit.
This is a 3D printed product, and as such in nrmal use, is strong enough for everyday use. It will not come off the strap, if fitted properly and not put through extreme environments.
Carefully locate the 2 screws on each side of each strap, that fix the strap to the ring watch. It is these 4 screws, that you need to remove and reuse in the new adapter. DO NOT LOOSE THEM, AS THERE ARE NO REPLACEMENTS.
Unscrew the screws, using as little pressure as possible, as you dont want to strip the threads. Once loose, you can use either your nail or a tiny blade to help you ease them from the watch. DO NOT LOOSE THESE.
Once you have removed both strap ends from the watch, simply locate the watch head on the adapter. It can go either way around.
Using the 4 screws, carefully push them back in the same holes, they came out of, and tighten them in, with the screwdriver, DO NOT OVERTIGHTEN THEM.
Now simply pass your NATO style strap, through the opening, and slide to the required position.
Fit the strap to the watch and ENJOY.
