Frequently asked questions.

D’s Time Service has CW21-certified watchmakers on staff. The Certified Watchmaker for the 21st Century credential was developed by the American Watchmakers-Clockmakers Institute with input from leading watch manufacturers to establish a high standard of knowledge and practical skill for servicing fine mechanical watches. Our head watchmaker also trained at the prestigious WOSTEP institution in Neuchâtel, Switzerland. Our team’s background includes training and certification associated with Rolex, Breitling, Omega and TAG Heuer, and we continue professional education to keep pace with current horological techniques.

Yes. D’s Time Service uses genuine replacement parts for the brands we service. If we cannot locate a genuine part for a brand or model we do not typically service, we will contact you and explain the best available solution. In certain cases, a manufacturer may require that the watch be sent directly to its service center to obtain or install a particular component.

A complete overhaul and service of a fine watch generally takes two to three weeks. The watch is completely disassembled, each movement component is inspected and thoroughly cleaned, and the case and bracelet are refinished when included in the approved work. Timing may vary if replacement parts are required or if the watch presents unusual complications. A qualifying complete service includes a documented warranty of up to two years.

Every watch case we open is evaluated and tested for the appropriate level of water resistance before it is returned. Necessary gaskets and seals are replaced, and the watch is tested with specialized equipment. Final water resistance depends on the model, age and physical condition of the case, crown, crystal and related components; we will tell you if the watch cannot safely meet its intended specification.

D’s Time Service offers a warranty of up to two years on complete overhauls and services for qualifying modern timepieces. Some older watches cannot be warrantied for the full two-year period because of age, condition or discontinued parts. Please ask us to confirm the warranty that would apply to your particular watch and approved service.

Yes. D’s Time Service accepts watches from customers throughout the United States. Please call us before shipping so we can confirm the current instructions. We recommend USPS Registered Mail with insurance for the watch’s full value. Once the watch arrives, we will evaluate it and contact you with an estimate—often the same day it is received.

Yes. Insurance companies often request a professional appraisal before adding a watch to a policy. D’s Time Service can appraise your watch for insurance purposes for a nominal fee. Appraisals can generally be prepared within 24 hours, depending on the watch and the information required.

Absolutely. With regular wear, a watch can lose its shine and luster before the movement is due for routine service. If the watch is running properly but the case or bracelet shows surface wear, an exterior refurbishment may restore much of its original appearance. We evaluate the watch first and discuss an appropriate level of refinishing, particularly for vintage pieces where preserving original lines and character is important.

Many leading Swiss manufacturers have historically recommended routine service at intervals of roughly three to five years, though the appropriate interval varies by manufacturer, model and use. Even when a watch appears to run normally, its oils and lubricants deteriorate over time, increasing friction and wear. Changes in accuracy, reduced power reserve, moisture, unusual sounds, or difficulty winding or setting the watch are all reasons to request an evaluation. It is better to inspect a problem early than to wait until the watch stops.

D’s Time Service does not charge to diagnose a problem or prepare a standard service estimate. Bring the watch to our downtown San Diego shop during business hours; walk-ins are welcome and no appointment is necessary. Some simple repairs may be completed while you wait. If you live outside the area, call us first—we may be able to offer initial guidance by phone or arrange for you to ship the watch. After an in-person inspection, we will explain the recommended work and obtain your approval before proceeding.
