Quick TakeThis isn't just another watch to tell you you're late. The Jazzmaster Day Date is your silent partner, the one that’s already thinking about Monday on a Friday afternoon. Its impressive 80-hour power reserve means it works through the weekend even if you don’t, ready to go the moment you are. The prominent day display arched at the top of the dial isn't just a function; it's a statement, a clear and present anchor to your week. The warm rose gold PVD against the cool steel and clean silver dial is the perfect metaphor for its character: a blend of approachable style and serious mechanical capability. It's a timepiece built for the person who plans their moves but is always ready for the spontaneous. It doesn't scream for attention, but its balanced design and reliable heart earn respect, a subtle nod to the wearer's appreciation for substance and enduring performance.

DescriptionThe timepiece is constructed with a stainless steel case measuring 42mm in diameter and 11.8mm in thickness. A PVD rose gold coating is applied to the bezel, providing a distinct two-tone aesthetic. The silver dial is protected by a sapphire crystal that features an anti-reflective coating to ensure maximum legibility under various lighting conditions. At the twelve o'clock position, a full day aperture is present, while a date window is located at the six o'clock position. An exhibition-style open case back allows for a view of the automatic movement within. The lug width is specified at 22mm, accommodating the supplied strap. Water resistance is rated to 5 bar, which is equivalent to 50 meters or 73 psi, making it suitable for daily wear and incidental water exposure.

Powering the watch is the Caliber H-40 automatic movement, which is distinguished by its extended 80-hour power reserve. This performance, nearly double the industry standard, ensures the watch will continue to run accurately for over three days without being worn or manually wound. The strap is a calf leather model, reference H6004251021, finished in brown and secured with a 20mm folding clasp. The combination of these materials and mechanical specifications results in a robust yet refined instrument for timekeeping.
