Tools are pretty iffy, and there is no list or reference sheet for what most of them even are or how to use them. Guides need improvement. Watch quality itself is not great. Afraid to wear the link strap due to sharp edges. Date wheel won’t stay where it’s supposed to go. Never got a response during the build when asking for help. Now I’m waiting for return options. NOTE: refund terms only apply to unopened, unassembled product, which is super shady and not at all clear on first read.
