Diamond Hut Jewelers

Diamond Hut Jewelers is a family-run jewelry store in Jersey City's Hudson Mall that also runs a watchmaker's bench on site. Alongside engagement rings and fine jewelry, the shop handles watch repair work, with servicing listed for Rolex and Seiko (including Grand Seiko) timepieces, up through full service and overhaul.

The shop says it is a Rolex authorized service center, a claim worth confirming directly with staff if that status matters for your particular watch or warranty situation. For Seiko and Grand Seiko owners, the shop lists general servicing without specifying whether that extends to authorized factory work.

It's open seven days a week, with longer hours on Saturday (until 7pm) and a slightly later start on Sunday (11am). The store is located right on NJ-440 at the Hudson Mall, making it a reasonably easy stop if you're already in that part of Jersey City. Appointments can be booked through the shop's website.

As a jeweler-watchmaker combination rather than a dedicated watch repair specialist, Diamond Hut fits buyers who already have a relationship with the store or who want a single local stop for both jewelry and watch servicing on Rolex and Seiko pieces.
