• Japanese-manufactured Orient F6B24 automatic caliber with 22 jewels, manual winding, and hacking seconds function.
• Poetic “Sun & Moon” day-night phase complication with an illustrated 24-hour rotating disc at 4 o’clock that tracks the movement of the sun and moon.
• “Suna no Hi to Tsuki” (砂の日と月) aesthetic concept: a sand-colored ivory dial structured in three levels that evokes the warmth of the first rays of sunlight on the horizon.
• A highly harmonious asymmetrical layout: day-of-the-week sub-dial at 10 o’clock, date window at 3 o’clock, and a double minute scale along the outer rim.
• A classically cut domed mineral crystal that enhances visual depth and pays homage to mid-20th-century watchmaking aesthetics.
• A stainless steel case measuring 41.5 mm in diameter and 47.0 mm from lug to lug, featuring smooth transitions and polished finishes.
• Transparent case back revealing the engraved oscillating weight and the mechanical movement in operation.
• Stylized hands and hour markers combined with applied Roman numerals for classic, high-contrast readability.
• Genuine leather strap with a comfortable stainless steel buckle.
• Water resistance of 30 meters (3 bar / 3 ATM) for protection against accidental splashes and everyday use.
• Exclusive edition from the Japanese Domestic Market (JDM) catalog, assembled in Japan.

Its three-dimensional dial is constructed of three overlapping layers to lend depth to each element. The asymmetrical composition masterfully balances the rotating sun-and-moon disc at 4 o’clock—which completes a full 24-hour rotation reflecting the passage of day and night—with a day-of-the-week sub-dial at 10 o’clock and a date window at 3 o’clock. The faceted Roman numerals and the double minute scale around the perimeter reinforce its distinguished appearance beneath the warm curve of its domed crystal.

At the heart of the timepiece beats the in-house Orient F6B24 caliber, an automatic mechanical movement with manual winding, a seconds stop function for precise synchronization, and a 40-hour power reserve, visible through its see-through case back. Complete with a genuine leather strap that complements the sand-toned dial, it is a timepiece with a captivating narrative that fuses traditional Japanese classicism with mechanical purity.
