Thought I would share this here. I ordered a ZF Hulk from intime. After the first wear the clasp buckle popped off when removing watch. I immediately sent an email to Ryan at intime to let him know. I was able to reinstall it and it was OK for 2 days of wear when it popped off again, and then again a3rd time a day after that. I asked Ryan to replace the watch or clasp. He said he cannot exchange a used watch but I can send back to him for repair. I asked him if he was covering the shipping costs but have not heard back yet. Has anyone ever experienced something like this?
