Choosing between quartz and automatic is mostly a question of how you want to live with your watch. Quartz is usually the easier choice when you want accurate timekeeping with little daily attention. Automatic appeals to people who enjoy a mechanical movement and are comfortable resetting or winding a watch after it has been off the wrist.
How each movement works
A conventional quartz watch uses an electrical power source and a quartz oscillator to keep time. Many use a replaceable battery, though the exact power system depends on the model. An automatic watch is mechanical: movement of the wearer's wrist winds a mainspring, which powers the watch. Some automatic movements can also be wound by hand; check the instructions for your specific caliber.
Key differences at a glance
| Consideration | Quartz | Automatic |
|---|---|---|
| Timekeeping | Generally more accurate in everyday use; check the stated accuracy of the exact movement. | Rate can vary with position, temperature, activity, and winding state. |
| Power and upkeep | Battery-powered models eventually need a battery change; the interval varies by movement and use. | No regular battery change for a conventional mechanical automatic, but it may stop when unworn and may need servicing. |
| Daily experience | Usually ready to wear after sitting unused, provided it still has power. | Rewards regular wear; may need winding and time setting after it stops. |
Quartz watches to compare
These three Infantry models show how quartz can serve different needs, from a compact field watch to large-format chronographs.
FIELD OPS Tactical Military Field Watch
A 41mm field watch powered by a Japanese quartz movement rated at ±15 seconds per month. It pairs a sapphire crystal with a day-and-date display, inner 24-hour scale, screw-down crown, luminous hands and indices, and 100M water resistance.
REVOLUTION AeroChron Flyback
This 47mm square quartz chronograph adds an instant-reset flyback function, date display, luminous hands and markers, a quick-release silicone strap, and 100M water resistance. Its reinforced polymer case uses a stainless steel top plate and a solid 316L stainless steel caseback.
REVOLUTION Chronomaster
A 47mm square chronograph built around the Seiko VD57 quartz movement. It offers 1/10-second chronograph timing, a date display, luminous hands, quick-release silicone strap, and 100M water resistance.
Automatic watches to compare
These three Infantry automatics offer different ways to enjoy a visible or self-winding mechanical movement.
REVOLUTION Autopilot Black
A 47mm square pilot watch with a Seiko NH35 21-jewel automatic movement. Its stainless steel case has a black PVD finish, sapphire crystal, exhibition caseback, date display, luminous hands, quick-release strap, and 100M water resistance.
REVOLUTION StealthOps Camo
This 47mm automatic uses the self-winding Miyota 8215 movement, listed with a 41-hour power reserve and 21,600-vph frequency. The camo-finished case is paired with an exhibition caseback, luminous hands and markers, quick-release strap, and 100M water resistance.
REVOLUTION SkeleTrak Pro
A 47mm skeleton watch that puts its Seagull TY2809 automatic movement and skeletonized rotor on display. The movement runs at 21,600 vph with a listed 40-hour power reserve; the watch also includes an exhibition caseback, luminous hands and markers, quick-release strap, and 100M water resistance.
Which should you choose?
- Choose quartz if you want a watch you can pick up and wear with minimal routine, or if everyday accuracy is your first priority.
- Choose automatic if watching and caring for a mechanical movement is part of the appeal, and you do not mind setting it again after a period off the wrist.
Before buying, compare the exact watch's movement, stated accuracy, power reserve or battery guidance, service information, and warranty. Those details matter more than broad promises about either category.
Common questions
Does an automatic watch need a battery?
A conventional mechanical automatic runs from a mainspring rather than a replaceable battery. Some other watch technologies combine mechanical and electronic elements, so check the model specification.
Will an automatic watch stop if I do not wear it?
It can stop after its stored power runs down. The time depends on the movement and how fully it was wound.
Is every quartz watch accurate to the same standard?
No. Accuracy varies by movement and conditions. Check the maker's specification for the watch you are considering.
