MTDelta Open-Heart Watch

The Watch

Founded in 2021, Maison Du Temps is a young French brand crafting quality watches at accessible price points. Its mission: satisfy discerning watch lovers and deliver a truly unique experience. The manufacture introduces a new lineup of timepieces under the name MTDelta - starting with this open-heart model. Beautifully executed, this watch comes housed in an octagonal case with a 40 mm diameter, crafted from 316L stainless steel. The vertical brushing across its surface creates a visually striking look that pairs harmoniously with the polished finish on the sides. With straight and curved lugs, the case has an assertive silhouette that sits comfortably on any wrist. On the right side, you'll find a screw-down crown bearing the brand's logo. Knurled for easy grip, it makes setting the hours and minutes a breeze. The dial is protected by a flat sapphire crystal ensuring excellent scratch resistance and optimal legibility. Finally, the screw-down case back features a sapphire crystal window inviting you to admire the movement's inner workings - and delivers 10 ATM water resistance.

The Dial

Clean, understated, and beautifully finished, the green dial on this watch makes reading the time a genuine pleasure. Its sunray finish frames an open-heart aperture between 6 and 7 o'clock, offering a captivating view of the movement beneath. A classic minute track runs along the perimeter, surrounding applied faceted baton indexes that mark the hours. Both the indexes and the two main hands are coated with a luminescent material for easy reading in low-light environments. The seconds hand sweeps across a dedicated sub-dial positioned between 4 and 5 o'clock. Finally, the brand name, movement type, and iconic five-petal rose logo are all displayed prominently on the dial.

The Movement

The heart of this watch beats with a Japanese automatic movement. The Miyota 82S5 caliber delivers a 42-hour power reserve and a precise, reliable analog display. It oscillates at 21,600 vibrations per hour.

The Strap

Elegant and refined, the strap on this model is crafted from green rubber. Flexible and comfortable, it features an ardillon buckle for a secure fit. It has a 20 mm lug width and will dress your wrist with effortless charm.

Water Resistance

With 100-meter water resistance - that's 10 ATM in proper watchmaking terms - this boldly styled timepiece is equally at home at black-tie events and in the water. Wear it in the shower, the bath, or the pool (even during intense laps). That said, our watch experts want to be clear: this model is not designed for any form of diving - freediving or scuba - and should not be exposed to high-pressure washers. Keep it simple: shower, bath, and swimming only - and never operate the pushers or crown while submerged.
