How to Care for an Automatic Watch: A Practical Owner's Guide

An automatic watch is a machine containing several hundred components, most of them smaller than a grain of rice, running continuously without interruption for years at a time. Considering that, it asks remarkably little of its owner. What it does ask for is specific rather than general, and the difference between a watch that runs cleanly for a decade and one that needs attention in year three usually comes down to four or five habits that take almost no effort once they are established.

Understanding the Power Reserve

Logues automatic calibres hold roughly thirty six hours of power reserve when fully wound, meaning the mainspring stores approximately that much running time once you stop moving. That figure describes ownership more completely than any other specification on the watch.

In practice it means a watch worn all day Friday will still be running through Saturday afternoon and will have stopped by Sunday morning. This is entirely normal behaviour and not a fault, though it is the single most common reason new automatic owners contact a service centre unnecessarily. A stopped automatic is simply a watch that has run out of stored energy, in the same way a car with an empty tank is not broken. Wind it, set it, wear it, and it resumes.

Winding It Correctly

If the watch has stopped, resist the instinct to shake it. Shaking spins the rotor at speeds and accelerations it was never designed to encounter and places real stress on the reversing wheels and the winding gear train. It is one of the few things an owner can do that causes genuine mechanical harm while feeling helpful.

Instead, take the watch off, hold the crown in its resting position, and turn it forward and away from you approximately thirty to forty times. You will feel a gentle resistance build as the mainspring tightens. Automatic movements incorporate a slipping clutch specifically to prevent overwinding, so you cannot damage the spring by continuing, but there is no benefit past the point where resistance is clearly felt. Set the time and date afterward, put the watch on, and normal wrist motion will maintain the wind from that point forward.

Wearing It, or Winding It Anyway

The lubricants inside a mechanical movement are formulated on the assumption that the parts they sit between will keep moving. A watch that sits completely still for months allows those oils to settle, migrate away from the surfaces they should be protecting, and thicken. Counterintuitively, a movement is generally happier being used than being stored, and long periods of complete stillness are harder on it than daily wear.

If a watch is temporarily out of rotation, wind it by hand for thirty seconds once a fortnight and let it run down naturally. That single habit, which costs less than a minute a month, meaningfully extends the interval between full services. A watch winder is a genuine convenience rather than a requirement, and it earns its place mainly if you own a watch with a complex calendar that is tedious to reset. For a day and date automatic it is entirely optional.

What Accuracy to Expect

A mechanical watch should not be judged by quartz standards, and a great deal of unnecessary disappointment comes from doing exactly that. A few seconds fast or slow per day is normal and comfortably within specification for this class of movement.

The rate genuinely varies with how tightly the mainspring is currently wound, with ambient temperature, and with the position the watch rests in overnight, since gravity acts differently on a balance wheel lying flat than on one standing vertical. If you find your watch consistently gains, try resting it dial up overnight rather than crown up, or the reverse. Small changes in resting position routinely shift the daily rate by several seconds, and many owners can regulate their watch to their satisfaction without a watchmaker simply by experimenting with where it spends the night. What is not normal, and does warrant attention, is a sudden change to a minute or more per day, or a noticeable collapse in how long the watch runs after being fully wound.

The Three Things That Actually Cause Damage

Magnetism is the most common and the most misdiagnosed. Laptop speakers, tablet covers with magnetic closures, handbag clasps, magnetic phone mounts and induction cooktops all produce fields strong enough to magnetise a balance spring. A magnetised watch runs dramatically fast, frequently gaining several minutes a day, and owners often assume the movement has failed. It has not. Demagnetising is a quick and inexpensive operation at any service centre, and prevention is simply a matter of keeping the watch away from speakers and magnetic mounts.

Shock is the second. Screwdrivers, gym weights, racquet sports and any kind of hammering transmit impacts directly into a balance staff that is designed to pivot on jewelled bearings, not to absorb blows. Take the watch off.

Adjusting the date near midnight is the third, and it is covered in detail elsewhere, but the short version is that between nine in the evening and three in the morning the date mechanism is partially engaged and forcing the quick set can shear fine teeth.

Cleaning and Daily Habits

Wipe the case and bracelet with a dry microfibre cloth at the end of each week. Sweat and skin salts accumulate between bracelet links and in the recesses behind the lugs, and they are the primary cause of a steel case looking dull long before it is actually worn. For a bracelet that has been neglected, a soft toothbrush and mild soapy water on the bracelet alone, kept away from the case, will restore it considerably.

Push the crown fully home before the watch goes anywhere near water. Every Logues automatic is rated 3ATM, which covers rain and splashes and does not cover swimming or showering, and a crown left half seated removes even that protection.

Service Intervals

Every four to five years is the sensible interval for a watch in regular use, and sooner if you notice the power reserve shortening or the rate drifting away from where it has always sat. A full service is a complete disassembly, ultrasonic cleaning of every component, relubrication with the correct oils at the correct points, regulation on a timing machine, and replacement of the case gaskets.

A watch serviced on schedule is a watch that gets handed on to someone. One that runs twelve years untouched usually needs replacement parts by the time it reaches a bench, because dried lubricant means metal running against metal, and that wear is not recoverable through cleaning.

Final Thoughts

None of this is demanding. Wind it properly rather than shaking it, keep it away from magnets, wipe it down weekly, respect the midnight window, and book a service every four to five years. Do that and the mechanism will outlast the interest of whoever bought it.
