Hi, if the situation is as portrayed seller maybe could have handled it better but than we´re "only" talking about $188 usd here. Why send as a gift in the first place - just pay 4% more and done.
Rep-strap: these sometimes are so bad they just come apart if You have them lying around for a while. Get a nice strap for the watch from +- $18 watchbandcenter.com
The moving dial is just a simple fix - unscrew/open the back in a dustfree environment and with a screwdriver tighten the 2 screws holding the movement, it´s really simple, no previous knowledge needed, sometimes new ones may arrive like that.
Buy a watch repair toolkit from ebay or amazon for some $15 to $20 USD as well, always comes in handy.
This is just to give You a thumbsup, try to enjoy the watch and take it as some learning money, much worse is to buy a $400 + shipping latest, ultimate model with a misaligned pearl, bad lume application and uncentered rehaut engravings with markers falling off.
