  • Does your timepiece have a round, flat mineral-glass or sapphire glass crystal?

  • Is it scratched, chipped, cracked, broken or even missing?

  • Is it rated water-resistant up to BUT NOT rated over 50 meters/165 feet?

Let us professionally replace your existing Sapphire Glass or damaged Mineral Glass  with a new Sapphire Glass Crystal.

Note: Due to the expertise and special tools required to professionally install watch crystals, they are not available for sale as parts only; you must send your watch to us to have this service done. Because of insurance liability against malfunction which could result in a life threatening situation, we do not replace crystals for watches that have thick domed crystals which are designed for diving and/or for watches that have a rotating time-lapse bezel. These timepieces are better serviced by their respective authorized service centers.

The following are excluded for sapphire crystal replacement: All chronographs; watches with rotating bezels; all perpetual calendar watches; all Citizen or Seiko, unless it is a STANDARD quartz model that has a FLAT/ROUND crystal with just a setting crown and without push buttons of any kind. Watches that are water resistant beyond beyond 165 feet or (50 meters) are excluded. We cannot replace the crystals on Citizen Eco-Drive, Chronographs and Divers or Seiko Chronograph, Perpetual Calendar models and Divers. All watches that have any other shape that IS NOT flat and round, or which have a calendar magnifier are excluded for the special sales price, however, the magnifiers can be added to a replacement for an additional $30

ABOUT SAPPHIRE GLASS: Sapphire Glass Replacement Crystals are made by crystallizing aluminum oxide, a very hard, crystal clear material at extreme temperatures. The Chemical Composition of synthetic sapphire glass is the same hardness as a natural sapphire gemstone used in the jewelry manufacturing industry. 

When aluminum oxide is heated to the crystallization point, synthetic sapphire is produced. Sapphire glass crystals are more expensive because diamond-coated saws are used to cut them into thin disk shaped pieces, which are then precision ground and polished into watch crystals.

Both natural and synthetic Sapphire are among the hardest substances known to man. A system for rating the relative hardness of various materials in the jewelry industry is called the Mohs scale of hardness.  Using this system, natural and synthetic sapphire measures 9 on the Mohs scale. A diamond has the highest rating of 10 on this scale.  Watch crystals made of synthetic sapphire are often advertised as "scratch resistant", meaning they are very difficult to scratch, but not impossible. A diamond can scratch a sapphire. Also man-made materials such as those made with or from silicon carbide that has a Mohs rating of between 9 and 10 is harder than sapphire.  Materials containing or those made with or from silicon carbide may sometimes be used to create simulated-stone surfaces in the manufacturing of Tile, floors, walls  (cinder-block) and furniture. Accidentally scraping your watch crystal against such surface's could result in a nasty scratch on even sapphire glass when struck just right.. and especially the regular mineral glass crystals. 

Like all crystals of any kind, they simply can not be made "unbreakable" and therefore CANNOT be guaranteed against scratching and/or breakage if struck by or against a hard surface mentioned above.

We offer professional precision fitted service for all high grade or other fine quality timepieces such as Omega, Bulova, Seiko, Citizen, Gucci, Movado, etc., and many others. 

IMPORTANT NOTICE:  All metric sizes and thicknesses of Sapphire glass crystals may not be immediately available for all watches in the aftermarket in which case you will be notified of any possible back order or delay, or if it is not available for your brand of timepiece.

Service Included with Every Crystal Replacement

  • State of the ART Ultrasonic cleaning of the case & metal band only in safe BIO-DEGRADABLE cleaners.

  • Clean & lube the setting crown gasket

  • Crown gasket and case tube inspected for precision fit to determine degree of proper sealing capacity

  • Carefully inspect and RODICO®-clean the movement battery contacts and check and adjust tension for maximum proficiency, if needed

  • Date code & install new EVEREADY ENERGIZER™ energy cell.

  • Precision oil the upper pivots and TURBO-SPIN the gear-train to ensure proper movement continuity.

  • Precision inspection of the sealing capacity of case and case-back areas to determine it's dependability.

  • Inspect and install new superior grade silicone O-ring rubber case-back gasket to insure optimum sealing capacity if needed.

  • Inspect watch band links and case lugs and replace damaged, broken or missing spring bars/pins/screws as necessary.

Although we afford every effort to ensure your watch will be more water resistant than when we received it, or improved to be as water resistant as the existing sealing surface of the case and case-back will allow, we do not guarantee it to remain Water Resistant for any length of time thereafter due to conditions beyond our control.  If we determine your watch to be rendered NON-submersible, it will be so noted on the service record. We may offer possible suggestions for resolve via email allowing you the opportunity to choose further service that may be needed if you so desire.
