This watch is the result of the second collaboration between Briston and Ocarat, embodying modern elegance and bold engineering. The cushion case crafted in cellulose acetate pairs beautifully with the watch's original dial. The domed sapphire crystal protects the dial while delivering exceptional clarity and durability. The caseback, both screwed-down and transparent, lets enthusiasts admire the intricate, artistic movement while ensuring outstanding solidity and water resistance. With dimensions of 40 mm x 40 mm and a thickness of 12 mm, this watch stands as a centerpiece for any fine watchmaking enthusiast.
The dial of this watch is a true visual and technical spectacle. Adorned with a stunning grand feu enamel finish, it captures light in a unique way, creating a subtle interplay of reflections.
A traditional and time-intensive technique, grand feu enamel involves a meticulous process in which layers of enamel are applied and fired at temperatures above 800°C. It demands an exceptional level of skill and expertise, delivering vivid, long-lasting colors. Adding another layer of sophistication, a spiral motif has been delicately embossed on the dial for a mesmerizing finishing touch!
The open heart at 9 o'clock adds an architectural dimension, offering a partial view of the inner movement that heightens the visual appeal and captivates watch enthusiasts. The slim, elegant hands sweep around the dial to indicate hours, minutes, and seconds with exemplary precision. The dial makes a bold statement with its deep navy blue color, which contrasts beautifully against the metallic tones of the hands.
Beneath the dial, this watch houses a sophisticated automatic movement, the NH38A caliber by Seiko Corp. Running at a frequency of 21,600 bph (3 Hz), this mechanism delivers remarkable precision and reliable performance. It features a power reserve of approximately 41 hours, keeping the watch running even after a full day off the wrist. With an oscillating rotor visible through the transparent caseback, the intricate details of this Japanese movement add genuine technical depth to the watch's aesthetic.
The strap of this timepiece is a work of art in its own right, crafted in bovine leather with a sophisticated alligator-embossed pattern. Its navy blue color pairs perfectly with the dial, lending an elegant, refined dimension that further elevates the watch's overall look. Fitted with a pin buckle, the strap ensures a secure, comfortable fit for a wide range of wrist sizes. With a lug width of 20 mm, it offers flexibility and all-day wearing comfort. The contrast stitching adds a refined detail that makes this strap even more appealing to the discerning eye.
With water resistance of 5 ATM, this watch is built to withstand pressure equivalent to a depth of 50 meters, making it perfect for everyday wear and light sports activities. It delivers reliable water protection without compromising style or functionality. This is further reinforced by the screw-down caseback, which adds enhanced solidity and reliability. Whether caught in an unexpected downpour or worn on a seaside adventure, this watch performs consistently without fear of moisture.
