With the widespread adoption of smart watches, and the general availability of quartz watches, the knowledge, use, care, and maintenance for mechanical and automatic watches has fallen by the wayside.
Lone Star Watch Group is committed to re-establishing the tradition of automatic watches to its supporters, while also providing the education and resources, necessary to ensure their timepieces stay functioning for a long time.
What is an Automatic Watch?
Automatic watches are a subcategory of mechanical watches. Unlike a quartz watch, mechanical watches use springs and gears to track time. No batteries are required for automatic watches and they charge through the movement of your wrist.
Watch Sizing
How a watch fits on your wrist depends on the shape of the watch, your wrist size, the case diameter and the lug to lug. The most important factor when considering the size of your watch is the lug to lug and your wrist size. In general, a watch is considered too big for your wrist if the lug to lug is longer than the width of your wrist.
Case Diameter - the length of the watch across the case not including the lugs or the crown
Lug to Lug - the length of the watch going from the end of one lug to the end of the other lug
Lug width - the length between 2 lugs on the same side.
most useful when searching for a new strap for your watch.
Please note; watch dimensions are standardized and measured in mm.
Bezel - a outer portion of the watch which surrounds the crystal. May be fixed or rotating.

All automatic watches require similar care and maintenance, for the best performance out of your watch:
ensure the crown of your watch is fully screwed in to prevent water leakage
screw down your watch with gentle pressure in a controlled manner to avoid cross-threading the crown
screw down the crown of your watch to the first amount of resistance, avoid overtightening the crown. Overtightening may damage your watches water resistance.
keep your watch away from strong magnets which may alter the function of the watches movement
If you noticed recent change to the performance of your watch, you may have accidentally exposed your watch to magnetization. L.S.W.G or any horologist can easily demagnetize and re-regulate your watch, but non-commercial use demagnetizers can also be readily purchased online for under $10.
Rinse off all watches with fresh waster after they have been exposed to sea water
Enquire about regular maintenance with L.S.W.G or a certified or trusted horologist
Avoid adjusting watch complications between 2100-0300 (9 P.M to 3 A.M)
"complications" refer to any function of a watch beyond displaying the time. These complication include a day/date window, chronograph functions, moon phase, other calendar functions, and GMT hand.
adjusting a complication between the times above can cause damage to the movement.
Set the time on your watch to 0630 or 1830 prior to changing a complication to avoid the watches danger zone.
Ensure watch is properly secured to your wrist to avoid physical shock damage from unnecessary falls or drops
Avoid adjusting the watches time or other complications while on wrist
Changing your watches setting while your watch is on wrist can put unnecessary pressure on the stem of the watch which may result in a stem break.
