Gruno's Diamonds

Gruno's Diamonds is a jewelry store in Madison, Wisconsin that also handles watch repair work, with a watchmaker on site who services Rolex and Tudor. The shop says it is an authorized service center for both brands, a claim worth confirming directly with Gruno's if that status matters for your particular repair or warranty work.

Beyond watches, Gruno's operates as a full jeweler, offering custom design, jewelry repair, and appraisals alongside its Rolex and Tudor collections. The business has been family-owned since 1953 and also has a Rockford location, though the Madison showroom at 7311 W Towne Way is the one listed here.

For anyone with a Rolex or Tudor needing service, battery work, or repair, this is a shop that specifically lists those two brands as part of its watchmaking capability, rather than a generalist who touches any make. If your watch is a different brand, it's worth calling ahead to confirm whether their watchmaker can take it on.

The store is open Monday through Saturday, closed Sunday, with consistent daytime hours most of the week. Contact them at (608) 829-1525 to check current turnaround times or to ask about pricing, since none of that is listed on their site.
