How often should you service an automatic watch?
Mechanical watches need regular servicing. If you've never owned one before, this might sound like it's a hassle, but it isn't. A professional service every few years is the price of owning a timepiece that will still be running fifty years from now, and it asks very little of the owner. In this guide we'll show you when to service your watch, what an automatic watch service actually does, what it costs, and which of our incredible quality MTM automatic watches are worth your consideration.
An automatic watch should be serviced every three to five years
This is really the bare minimum you should be considering. Modern movements with synthetic lubricants can sometimes stretch to five years or more. Heavily-used chronographs often need attention sooner, around every four years. For most owners, three to five is the sweet spot.
Put that in perspective - most people service their car twice a year. Your watch doesn't ask anywhere near as much maintenance as that. And a well-serviced automatic watch will run for generations on a maintenance schedule that asks very little of you.
Why an automatic watch needs servicing
An automatic watch is hundreds of tiny metal parts running against each other at high speed, kept moving by a thin film of specialist lubricant. Over time the lubricants degrade, and the rubber gaskets that seal the watch against water slowly harden and compress.
You can't see this happening from the outside and you won't even notice it's happening. Your watch can keep accurate time for months while the internal components quietly wear out. By the time accuracy slips or moisture gets in, damage is already done. Scheduled servicing stays ahead of that - we refresh the lubricants and swap the gaskets on a predictable cycle, and your watch keeps running the way we built it to.
What servicing actually involves
A qualified watchmaker opens the watch, takes the movement out, dismantles it, cleans every component in an ultrasonic bath, replaces the lubricants, swaps the gaskets, reassembles everything, and tests for accuracy and water resistance. The watch comes back running as well as it did the day you bought it.
This is maintenance, not repair. A service is scheduled and routine; a repair is what you pay for when servicing was skipped. The point of regular servicing is to keep you out of the repair conversation entirely.
Turnaround is usually a few weeks. There's nothing you need to manage in between - send it in, get it back, keep wearing it.
Signs your automatic watch needs a service
Most owners don't watch the calendar. They notice something's off, and they send the watch in. Here's what to look for:
- Timekeeping drift - the watch gains or loses more than twenty seconds a day.
- Shortened power reserve - it used to run forty hours off the wrist, now it runs twenty-five.
- Moisture or fogging under the crystal - the seals have failed and it needs attention now.
- Stiff or noisy winding - the lubricants have dried out and the parts are grinding.
- The watch stops while you're wearing it - the movement is struggling and needs to be looked at.
Any one of these and it's time to have your watch serviced.
How to keep your watch healthy between services
A few simple habits keep your watch healthy between services.
Wear it regularly. The best thing for an automatic watch is consistent wear. Motion keeps the lubricants distributed and the components loose. A watch that sits in a drawer for months will need servicing sooner than one worn daily.
Wind it if it sits. If your automatic is part of a rotation and gets skipped for weeks at a time, give it thirty to forty crown turns once a month.
Store it properly. Original box or a watch roll, away from humidity, direct sunlight, and heat.
Avoid strong magnets. Phones and handbag clasps are fine. MRI machines and industrial magnets are not. Magnetism throws the timing off - easy to correct, but worth avoiding.
Rinse saltwater off. If you've been in the ocean or sweating hard, a quick rinse under fresh water and a wipe-down keeps the gaskets and strap in good shape.
How much does a service cost?
Expect to pay $250 to $500 for a complete service on a standard three-hand automatic. Watches with chronographs or complications cost more - typically $600 to $1,000 - because there are more components to clean, lubricate, and test.
Worth remembering: you're paying this every three to five years, not every year. Annualised, it's a modest line item on a watch that will probably outlast you. A documented service history also preserves resale value - collectors pay a premium for a mechanical watch with clean records.

The best MTM automatic watches you can buy
Every one of our automatic watches lives in the Elite collection - hand-built in America, engineered for hard use, and designed to be handed down. Each watch below runs a Swiss or Japanese automatic movement built for real-world use: field conditions, extended deployments, daily professional wear - not just the display cabinet.
The Silver Oconus is the access point to our automatic range. A clean classic dial, a Miyota 9100 movement, and a brushed grade 2 titanium case designed to wear well across a boardroom, a flight deck, and everywhere in between. Exhibition caseback so you can watch the movement at work. Limited to 500 individually numbered pieces.
The US-744X is built for operators. A Grand Seiko automatic movement, a grade 5 titanium case with forged carbon fiber, and tritium tubes that glow for 25 years without any external light source. Depth-rated to 500 metres with a helium release valve. Ships with a titanium bracelet and two additional straps.
The flagship of our Elite line. A COSC-certified Swiss chronograph movement, Black DLC-finished grade 2 titanium, and our titanium ball-bearing bracelet - the only watch in the world built with one. Only 50 pieces exist. An incredible watch that will last you an entire lifetime.
Why MTM builds automatic watches differently
We test our automatic watches across the full range of environments our wearers actually work in: high altitude, desert heat, tropical humidity, cold climates, and sustained water immersion. An automatic movement is only worth owning if the watch holding it stays reliable under pressure. Every MTM automatic is built to that standard - not to a display cabinet standard.
We've been hand-building watches in the United States for over 35 years. Each one is assembled by skilled craftsmen and women with an attention to detail that production-line manufacturing can't replicate. When you buy an MTM automatic, you're buying a purpose-built mechanical watch engineered to be handed down. Browse the full range of automatic watches to find yours.
Frequently asked questions
A properly serviced automatic watch can last lifetimes. Many are passed down across generations. The mechanical movement can be serviced indefinitely as long as parts are available - which is why quality automatics hold their value the way they do.
Usually it just needs more wear. Automatic watches self-wind from wrist motion - if the watch is worn lightly, or set down for a full day, the power reserve runs out. If it's stopping during regular daily wear, it's time for a service.
No. Automatic watches use a slipping-clutch mainspring that physically prevents overwinding. You'll feel resistance when it's fully wound - when you feel it, stop - but you're not at risk of damaging it.
Daily wear keeps it running on its own. If the watch is sitting unworn, wind it once a month - thirty to forty crown turns fully loads the mainspring.
Yes - and on the normal three-to-five-year schedule. Lubricants actually dry out faster in unworn watches because the parts aren't moving.
Manufacturing defects are covered by our warranty. Routine scheduled servicing is a separate programme - sending your watch back to us is the most straightforward way to keep it running for life.
