Northeast Watch Works transformed my Seiko with stunning sapphire crystal upgrades!

Several watches are neatly arranged in a cushioned watch box with separate compartments. The focus is on a watch with a black strap and another with a silver casing and black face.

I was impressed with the glass bead blasting service. My watch looks brand new and the battery replacement was quick and efficient. Highly recommend Northeast Watch Works!
