My order number is T59336. The watch (GM-106-2 Toronto - Silver) has six flat-head screws holding the case-back onto the watch.  The watch was received with 2 defective screws.  One screw was undersized and fell out of the watch into the box.  The second screw was free-wheel spinning in its hole without getting tight.  Tufina sent me 8 replacement screws to try and fix the watch without returning it.  I tried all 8 new screws, but my conclusion is now that there were 5 defective holes which have undersized threads.  Only one screw tightens properly, and 5 of the screws free-wheel spin without getting tight.  I included the extra 8 screws in a plastic case inside the box.  The watch is brand new and has never been worn.  To my knowledge, there are no scratches or other defects. I spoke with Peter from the Tufina Care Team, and he told me that Tufina agrees to replace my watch with another model, which is very similar, but it does not have any screws holding the case-back on.  Please replace with LAGOS | GM-113-2 | BLUE.
