A full service on a Swiss mechanical watch usually starts near $800 and can pass $1,600. Bob's Watches, a pre-owned Rolex dealer, put the standard range for a Rolex overhaul at $800 to $1,600 in August 2025, with complex references past $2,800. The interval, not the invoice, decides the real cost of owning one.
A mechanical movement is a small machine that wears while it runs. Wikipedia's entry on the mechanical watch is blunt about the duty of care: such watches eventually require periodic cleaning, lubrication and calibration by a skilled watchmaker. Owners who plan for that work pay less per day of use than owners who do not. This connects to our earlier piece, What Happens During 200 Hours of Finishing on a Mechanical Watch Movement.
What Happens During a Complete Service?
The watch comes apart completely. The movement is disassembled, cleaned, re-oiled and calibrated, then the case is resealed. Wikipedia's craft summary lists cleaning, lubrication and calibration as the core cycle, done by hand at the bench. The dial and hands come off as well. Each part is checked for wear. Worn pieces are replaced, not just cleaned.
OMEGA's own service pages describe its Complete Service as work that restores both function and aesthetics. The brand attaches a twenty-four month warranty to each intervention. The invoice buys a defined period of cover, not just a cleaned movement. Wikipedia's mechanical-watch entry keeps the scope honest: the work repeats for as long as the watch runs.
How Often Does the Interval Fall Due?
OMEGA recommends a complete service every 5 to 8 years at an authorised centre. The pace is set by use and environment, per the brand's guidance. Rolex advises roughly ten years, according to Bob's Watches' August 2025 cost guide, which adds that daily wear pulls that forward to every 5 to 7 years.
Intervals have stretched over time. Modern lubricants last longer than old ones. Use still matters more than the calendar. A watch worn every day burns lubricant faster than a drawer piece. A dress watch worn to dinner twice a month can wait. A dive watch taken to the pool cannot. Water, shock and magnetism shorten the gap further.
Where Does the Money Actually Go?
Labor, not parts, drives the bill in most cases. Bob's Watches reports that price follows movement complexity and arrival condition, not the watch's market value. Worn parts push complex chronographs and precious-metal references past $2,800 once replacements enter the job. For related coverage, see Which Watches Hold Their Value?

A service centre also fits new gaskets, pressure-tests the case and issues a fresh warranty on the work. Each step is bench time by a trained watchmaker. That is what the premium over a quick polish pays for. Records matter here too. A stamped service file documents each visit.
How Does Service Change the Cost per Wear?
Spread the arithmetic out. Divide Bob's $800 entry figure across an eight-year interval at OMEGA's outer limit and the bill lands near twenty-seven cents a day. Even a $1,600 invoice over the same stretch stays under sixty cents a day. That is less than most owners spend on straps.
The number rewards long ownership. A watch kept thirty years and serviced on schedule carries a steady cost per wear. A neglected one risks a parts bill no plan can soften. Dried oil grinds at the pivots until metal, not lubricant, takes the load. A dated service file also tells the story of care. Paperwork of that kind travels with the watch. Ask for the old parts back, too. Most centres return them in a small bag. Seeing the worn pieces makes the next invoice easier to read.
Conclusion: The Interval Is the Real Price Tag
The sticker price of a mechanical watch is only the entry fee. The service interval, running every 5 to 10 years depending on the maker, is the line item that sets lifetime cost. Budget roughly $800 to $1,600 per cycle at manufacturer rates. Check what the warranty on the work covers. Then the cost per wear stays modest, and the watch earns its keep. Buy the movement you will actually service, not only the one you admire.
