Ocean Day And Night lndicator Bright silver blue

Time flows endlessly, much like the sea beneath moonlight. Inspired by the balance of light and shadow, this mechanical watch interprets the rhythm of day and night as a continuous dialogue between motion and stillness.

At the center of the design, a hand-engraved guilloché dial shimmers in deep ocean blue, echoing the movement of waves through time. Above it, the sun-and-moon display evolves naturally as the hours pass, creating a visual transition from sunrise to twilight. Powering this transformation, our custom-modified Miyota 9015 movement delivers precise day–night functionality with proven stability and accuracy.

Meanwhile, the classic case profile enhances the watch’s refined presence, while the genuine alligator leather strap adds warmth and timeless elegance. Together, polished curves and intricate textures reflect a philosophy rooted in restraint, balance, and enduring craftsmanship.

Beyond aesthetics, we serve as a professional OEM mechanical watch manufacturer, offering flexible customization solutions. You can engrave your logo, adjust movement functions, or refine design details to match your brand identity. As a result, this timepiece becomes more than a watch—it becomes a personal expression of mechanical artistry and storytelling.
