Diamond Cellar

Diamond Cellar is a jewelry store in Dublin, just northwest of Columbus, with a watchmaker on staff who handles work on Rolex, Tudor, and Patek Philippe watches. The shop says it is an authorized Rolex and Tudor service center, which would mean movement servicing and warranty-covered repairs go through official channels for those two brands rather than an independent watchmaker.

This is not a full-service watch repair outfit in the sense of handling every brand or basic jobs like battery swaps — those aren't offered here. If your watch is a Rolex, Tudor, or Patek Philippe and needs servicing, polishing, or a repair, this is a place to ask. For anything else, including a simple battery change on a quartz watch, you'll want to look elsewhere.

The store sits on Sawmill Road and is open seven days a week except Sunday, with consistent hours from 10am to 6pm Monday through Saturday. Given the brand focus and the claimed factory authorizations, expect this to function more like a boutique watch counter attached to a jewelry store than a general watchmaker's bench — appointments are likely worth booking ahead for service drop-offs, and it's worth calling first to confirm current wait times and whether your specific watch model and issue are something they take on in-house or send out.
