The automatic 317B131 watch from Maison Pierre Lannier showcases a unique and elegant skeleton dial. A refined choice for men who appreciate clean, timeless style. This timepiece features a stainless steel case measuring 42 mm in diameter and 13.5 mm thick. The round dial is protected by a mineral crystal for scratch resistance. At 3 o'clock, a screw-down crown lets you set the time with ease. The transparent snap-on case back provides water resistance of 5 atmospheres.
What makes this watch truly special is its dial - the movement is fully visible to the naked eye. This skeleton dial showcases the black dial surface, a magnificent gold-tone tourbillon, and purple rubies. To enhance luminosity, the brand has applied a sunray finish to the dial. Around the edge, the hour indices appear as Roman numerals in silver-tone stainless steel. At the center, three hands display the hours, minutes, and seconds - with the hour and minute hands being luminescent. A minute track runs along the outer edge for precise minute reading. The brand signs its name below the 6 o'clock index.
This timepiece is powered by an automatic movement that drives all three hands for hours, minutes, and seconds. Sourced from the Miyota manufacture - of Japanese origin and renowned for its reliability and precision - it lets you admire the rotor and tourbillon in motion.
The strap accompanying this jewelry timepiece is crafted in stainless steel, silver-toned for a sleek, refined look. The lug width is 20 mm, and it fastens securely with a double deployment clasp.
With water resistance of 50 meters - or 5 ATM in watchmaking terms - this timepiece can handle a splash but isn't built for prolonged water contact. You can get away with wearing it in the shower every now and then, but to protect the quality and precision of the movement, our watch specialists strongly recommend keeping it away from baths, pools, and the sea. No swimming, no diving, no extended immersion.
