A lab-grown diamond is chemically identical to a mined one. It has the same hardness, the same brilliance, and the same need for sensible care. While the diamond is extremely hard, the surrounding materials such as leather, polished steel, seals, and coatings still require careful handling. If you want your PASCAL timepiece to look sharp five years from now, the habits you build today matter more than any single cleaning session.
Why Lab-Grown Diamonds Need the Same Care
Lab-grown diamonds rank ten on the Mohs scale, just like mined diamonds. That means they resist scratching, but the metal around them does not. The 316L stainless steel case, the sapphire crystal, and the leather strap all age differently. Long-term wear depends more on how the full watch is treated than on the hardness of the diamond itself.
The Three Enemies of a Diamond Watch Finish
Moisture is the biggest threat to leather straps and internal gaskets. Abrasives, including household cleaners and gritty cloths, scratch metal and dull polished surfaces. Impact, even minor bumps against door frames or desks, can chip crystal edges and misalign hands. Most cosmetic damage comes from repeated exposure to moisture, abrasives, or accidental impact.
Daily Habits That Extend the Life of Your Watch
Take the watch off before the gym, the pool, or any activity involving cleaning chemicals. Sweat and chlorine degrade leather quickly, and sudden temperature shifts can stress the seals. Overnight, store the watch flat in its original box or on a valet tray. Hanging it over the edge of a nightstand twists the strap and warps the shape. Rotating between watches also reduces continuous moisture and skin-oil exposure on the strap.
How to Clean a Diamond Watch at Home
For leather straps, use a barely damp microfiber cloth to wipe the surface, then dry it immediately. Never submerge leather. For metal bracelets, rinse gently under lukewarm water, pat dry with a soft towel, and finish with a microfiber pass to restore shine. Clean the case and crystal with a dry or slightly damp cloth. Avoid paper towels, which are more abrasive than they look. PASCAL watches use sapphire crystal, so the glass itself is highly scratch-resistant, but the anti-reflective coating on some models benefits from gentle treatment.
What 3-5 ATM Water Resistance Actually Means
A 3 ATM rating handles rain and handwashing. A 5 ATM rating adds confidence for light splashes and brief immersion. Neither rating means you should swim or shower with the watch. If water does get inside, stop using the crown immediately and have the watch inspected. Water behind the crystal is a sign that a seal has failed.
When to Send Your Watch in for Professional Service
If the watch gains or loses more than a few seconds per day, if the crown feels gritty, or if moisture appears under the crystal, it is time for service. PASCAL's Swiss quartz movements are reliable, but the gasket, battery, and hands all benefit from periodic attention. A professional service every two to three years is a reasonable interval for a daily wearer.
PASCAL's 24-Month Warranty
Every PASCAL watch comes with a 24-month warranty covering material and workmanship defects. It does not cover loss, normal wear and tear, or damage from impact and moisture exposure. Keeping your watch within its rated limits and cleaning it regularly protects both the finish and your coverage. For full terms, see the warranty page.
