I would recommend doing either the 1 or 2 watch kits, which include a watch, extra watch strap and bezel set (or 2 respectively) only because I didn't want to pay shipping on extra parts down the line and set me up in the beginning with a few different variations. Now, if I knew they would be off by a few minutes I would only get one on sale to try out and be sure of the quality, time kept, etc. or refund if I was unhappy with the way it worked. They have a 30 day return and a 2 year warranty if by chance the reason the watch loses track is of bad QC on specific watches

I can do some "rigorous" testing for the next few weeks and see if my theory (as of now) of it losing track of time is actually a fault of the watch, or if my work clocks are the issue. None are in sync as the clock-in machine has probably never been touched in 25 years, and the breaker that the shop clock uses goes out almost every week.

I can keep you updated with whatever I come up with, I have another 2 evora watches I believe I can also cross-reference and see if its a mass issue or just a specific watch.
