AGELOCER Tourbillon Watches Men Original Full Transparent Crystal Case Limited Edition, Luxury Sport Skeleton Waterproof Manual Mechanical Watch, Luminous Reading, Gift — Open-Box, 64% Off

2025 Inaugural Year of World Glacier Day, Agelocer called for greater public attention and participation in addressing climate change. Swiss Chief Designer Etienne Ruffieux grand launch the 'Never-Melting Ice 2.0' fully transparent crystal case free-sprung balance Tourbillon Watch, This timepiece was awarded the French National Design Award for its outstanding design and is available in a limited edition of 299 pieces worldwide.

The watch features a sapphire crystal glass face and an Agelocer-exclusive K9 crystal case with 95% light transmittance. Treated with annealing hardening and silicon carbide Deposition technology, it achieved a hardness of Mohs 8. This exceptional hardness prevents scratches, ensuring the watch remains pristine over time. The crystal case's high transparency allows for a clear view of the exquisite mechanical artistry of the skeletonized flying tourbillon.

Independently developed CAL9001 free-sprung balance flying tourbillon movement, manual winding, 28,880 vibrations per hour, 25 ruby bearings. Features high-end finishing including satin brushing and beveled edges, engraved brand logo with gold-stamped. Dual mainspring series technology delivers 80-hour power reserve (twice that of standard tourbillon movements). This technology ensures more uniform and gradual mainspring release, resulting in enhanced timekeeping precision and stability.

The CAL9001 tourbillon movement features the exclusive free-sprung micro-adjustment technology typically reserved for luxury timepieces. This free-sprung system eliminates the need for a balance spring regulator, thereby overcoming the timing inaccuracies caused by regulator displacement in conventional mechanical movements. This ensures the watch delivers enhanced precision and stability in timekeeping.

The watch is water-resistant to 50 meters. It features a food-grade translucent silicone strap with a butterfly double-push buckle, offering waterproof, sweatproof, and corrosion-resistant properties for comfortable and durable wear. Featuring Super-LumiNova Luminous hands and hour markers. We provide a three-year worldwide warranty.

New watch has no initial power reserve; please wind the crown clockwise for 60-80 turns to replenish power (you can judge the remaining power by the tightness of the movement's mainspring barrel). This tourbillon watch can run normally for 80 hours when fully wound. We recommend winding it 30 turns every 1-2 days to replenish power and maintain the watch’s optimal timekeeping performance.

If you encounter any issues, please feel free to contact us via Amazon, and we will provide you with a satisfactory solution within 48 hours.

We compared the refractive index, light transmittance, Mohs hardness, impact resistance, cost, etc. for the case material. In order to allow the public to buy high-quality and reasonably priced tourbillon, we selected K9 crystal. The refractive index is excellent at 1.52, close to natural crystal, and the light presents a brilliant luster after refraction. The light transmittance is greater than 92%, higher than ordinary glass (about 80-88%), and the visual clarity is close to sapphire glass (light transmittance is about 95%).
