a case with excellent quality

Andre Kowalczyk
Good quality for the price.

Good finish. Pushers work smoothly. For the price you even get some minimum water resistance. The glass, I suppose, is acrylic. Perhaps I will one day replace it my mineral glass but for now it will do.

moonwatch style case and dial

Received my items in a timely manner. The case and dial are beautiful, no issues with quality, they are very nice. I bought a seagull st1903 movement and it fit right in without any problems. I am very satisfied with the product and service I received.
