Watch Guide
Effective Oct 23, 2026
This page explains how to wind or start, set, size and look after a Zyntrie watch, mechanical or quartz, and how to read the figures printed in each listing.
Because a mechanical watch has no battery
Mainspring: the coiled spring inside the movement that stores the energy to run the watch.
Movement: the mechanism inside the case that turns that stored energy into the motion of the hands.
Automatic movement: a movement that winds its mainspring from the motion of the wrist.
Hand-wound movement: a movement whose mainspring is wound by turning the crown.
Every Zyntrie men’s watch is one or the other, and the listing says which. Neither kind holds a battery, so a stopped mechanical watch is wound before anyone calls it faulty.
If the watch is hand-wound
Wind it once a day, at roughly the same hour. With the crown pushed in, turn it clockwise, away from you, until it stops turning freely, then stop. Forcing the crown past that point can damage the mainspring.
If the watch is automatic
Wearing it winds it. A watch that has been off the wrist long enough to stop needs a start: wind it by the crown if the listing says it can be wound by hand, usually 20 to 30 turns, or move it gently from side to side for a minute. Then set the time and wear it.
Power reserve: the number of hours a fully wound watch runs before it stops. The listing gives the figure.
If the watch is quartz
Quartz movement: a movement that runs on a small button cell and keeps time with a vibrating quartz crystal.
The women’s and unisex watches are quartz, and none of them needs winding. A quartz watch can arrive with its crown pulled out to save the cell: push the crown in, set the time and it runs. When it starts losing time or stops after months of wear, the button cell is spent, and a watch shop or jeweler can fit a new one in a few minutes. A quartz watch that does not run when it arrives is a technical defect under the Refund and Returns Policy.
So that the crown is used the right way
Crown: the knob on the side of the case that winds the mainspring and sets the hands.
Screw-down crown: a crown that screws onto a threaded tube to seal the case.
On most models the crown pushed in winds the watch, the first pull sets the date and the second pull sets the time. A screw-down crown is unscrewed counterclockwise before winding or setting and screwed back down, firmly but without force, afterward. The manual in the box gives the positions for your model.
Unless the date is set late in the evening
Many date mechanisms are busy changing the date between 9:00 PM and 3:00 AM. Turning the date by hand while the hands sit in that zone can harm the mechanism, so move the hands to 6:00 first, set the date, then set the time.
Since every mechanical movement gains or loses some seconds
Accuracy: the number of seconds a mechanical movement gains or loses in a day.
The listing prints the maker’s daily tolerance when the maker states one. Timing inside it is normal for a mechanical movement. The rate also shifts a little with temperature, with the position the watch rests in overnight and with how fully it is wound. A quartz watch keeps much closer time than a mechanical one.
Provided the rating suits the water
Water resistance rating: the pressure, given in meters or ATM, that a sealed case withstood in testing. It is not a safe diving depth.
| Rating on the listing | Fine for | Not for |
|---|---|---|
| 30 m (3 ATM) | splashes and hand washing | swimming |
| 50 m (5 ATM) | light swimming | snorkeling or diving |
| 100 m (10 ATM) | swimming and snorkeling | scuba diving |
Push the crown in, or screw it down, before the watch meets water, and never press the crown or pushers under water. Hot showers, saunas and soap wear down the seals faster than plain water.
Even if no magnet seems close
Magnetism: the pull of a strong magnet on the steel parts of a movement, which makes a mechanical watch run fast.
Speakers, magnetic phone cases, tablet covers and laptop lids carry strong magnets. A watch that suddenly gains minutes a day after sitting near one is usually magnetized. A watchmaker can demagnetize it in a few minutes, and it is not a defect.
So that the watch fits your wrist
Case diameter: the width of the case across the dial, not counting the crown.
Lug width: the distance between the two lugs that hold the strap, which sets the strap width that fits.
Wrap a soft tape measure or a strip of paper around the wrist where the watch will sit and read the length. A 6.5 in (16.5 cm) wrist suits a strap whose listed fit includes 6.5 in. A listed case diameter allows 1 mm either way, so a 40 mm case measured at 40.8 mm still matches its listing.
Should a bracelet need shortening
Bracelet link: one removable segment of a metal bracelet.
A watchmaker or jeweler can take out links to fit your wrist. Keep every removed link and its pin in a small bag; a return has to include them.
As long as the watch is cleaned gently
Wipe the case and crystal with a soft dry cloth. Rinse a metal bracelet in fresh water only when the rating allows it and the crown is pushed in, then dry it. Keep leather straps away from water, perfume and long sun, and store the watch away from magnets and hard knocks.
Although service intervals vary
Opening the case, regulating the movement and replacing seals are jobs for a watchmaker. Most watchmakers suggest a service every few years; the manual gives the maker’s interval when it states one.
Even though you can return a watch within 30 days
Try a new watch on before removing the protective films from the case back and clasp, and keep the box, the manual and the tags. A watch that shows wear or comes back without its links cannot be refunded under the Refund and Returns Policy.
