This watch is too refined to be just a tool watch.
It has a slightly dressy feel, but it matches well with almost any outfit. As someone who frequently travels between South Korea and the United States, the dual-time functionality has been especially useful.
I'm very impressed with this Edifice model. This was my first purchase from Watchspree, and the service was excellent. The staff were friendly and helpful throughout the process. I'll definitely be buying my next watch from them as well.
