I have been here a couple times. One time was to fix my watch band and another time to replace the batteries in a different watch. Both times i thought the prices were fair and affordable. The service is also fast and friendly. Would highly recommend if you need to get your watch or jewelry serviced. Its a cute little family owned store so you also feel great after for supporting local businesses.

In my opinion they do it the old fashion way with layaways they write it down and the people treat you awesomely not like a number or just a commission sale sometimes like the mall I have purchased several pieces from them and I could not be more happy with the attention to detail and the meticulous workmanship of some of their pieces like in the estate cases really amazing deals in my opinion. I recommend them to people I know hands down with repairs and special orders as well and with items on layaway, any question you have I will answer them.
