Eh, can be good or bad. It is grey market after all. The warranty isn’t “worthless” but it’s not great. Basically anything that goes wrong they will fix it, not swatch. So you have to mail it to them and it can take ages to fix. But from what I have heard, Swatch warranties are garbage too.

I actually bought a khaki mechanical from the exchange a few years ago and it came from jomashop. The mainspring broke (which apparently can happen) and while jomashop did honor the warranty it would have taken so long to get back that I just claimed it on insurance and sold it for parts
