Frequently Asked Questions (FAQ)

Does the OLEVS 9910 open-heart watch require battery replacements?

No batteries are ever required. The OLEVS 9910 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 across all internal calendar and timing modules.

How durable is the open-heart window and the steel bracelet against daily wear?

The watch is built for robust daily performance. The front open-heart exhibition window and main dial utilize high-hardness coated protective crystal mirrors engineered specifically to withstand daily friction, minor impacts, and micro-scratches. The 20mm textured steel bracelet is constructed from solid links secured by a durable double snap fastener (butterfly clasp), ensuring structural integrity through years of executive wear.

Is this 152g grand complication watch suitable for routine water exposure and rain?

Yes. Despite its substantial 152g heavyweight feel and complex multi-layered architecture, 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 internal mechanical lubrication and water-resistant seals, avoid wearing the watch during hot showers, saunas, or deep submersion.
