Great service by Watchspree. I will definitely buy again. The only concerning bit is that I hope their delivery partner will be a bit more careful and take into consideration how they treat the packages since some items can cost quite a bit.

Loved this particular iteration of the GMT with a slightly unique dial and rose gold accents at an affordable price point
