True horological distinction lies in witnessing the living heartbeat of a precision mechanical engine. The OLEVS 9920 is engineered for the discerning gentleman who appreciates intricate micro-engineering and refined aesthetic luxury. Designed with a comprehensive full exhibition skeleton dial, this timepiece strips away conventional barriers to showcase the synchronized dance of golden balance wheels, gears, and mainsprings beneath the glass. Perfectly proportioned within a classic 40mm stainless steel case and adorned with brilliant diamond-accented hour indices, this watch commands respect and attention in executive boardrooms and evening celebrations alike.











Beneath its transparent, architecturally stunning exterior operates an original self-winding mechanical caliber, constructed to deliver enduring daily accuracy and reliable self-winding performance without ever needing a battery:
No batteries are ever required. The OLEVS 9920 is driven by an original self-winding automatic mechanical movement. It harnesses kinetic energy from the natural daily movement of your arm. Wearing the timepiece regularly keeps the internal mainspring continuously wound, ensuring reliable, uninterrupted precision day after day.
The watch is built for robust daily performance. The front and rear exhibition windows utilize high-hardness coated protective mirrors engineered specifically to withstand daily friction, minor impacts, and scratches. The internal skeletonized bridges are securely anchored within the 12mm solid steel case architecture, ensuring structural integrity through years of executive wear.
Yes. The timepiece is officially tested and certified for 30M (3 ATM) water resistance. This robust specification ensures dependable daily defense against routine water splashes, unexpected rain, and hand washing. To preserve the internal mechanical lubrication and protective seals, avoid wearing the watch during hot showers, saunas, or swimming submersion.
