MARIANA TRENCH – Limited series of automatic watches with relief of the Mariana Trench, water-resistant to 20 ATM

The detailed measurement of the seabed has been an ambitious goal of scientists all over the world for decades and is as dangerous as it is costly. Although one glance at a world map gives the impression that the earth and the seabed surface are completely mapped, only a fraction of it has actually been explored. In this context, the Mariana Trench and the history of its exploration are particularly fascinating. This deep-sea trench is around 2500 kilometers long and lies in the western Pacific Ocean. Its maximum depth, and thus the deepest point in the ocean, is approx. 11,000 meters (approx. 36,000 feet). Like the Mariana Islands, the trench was named after the Spanish Queen Maria Anna of Austria.

Functions and design:
The watch series MARIANA TRENCH shows a dial with a pronounced relief of the Mariana Trench beneath its scratch-resistant sapphire crystal. At its lowest point, the dial breaks through the border with the movement and, through drilled craters, reveals some of the otherwise hidden ruby bearing stones and parts of the train. The 24-hour display is designed as a compass rose, with the pointer, shaped like a compass needle, showing the 24-hour time with its red tip. The date is at the 6 o’clock position. Maritime dew appliqués frame the date and name plateau.
The elaborate 10-piece steel case with ion-plated blue, brown or black bezel has a diameter of approx. 46 mm and a thickness of 14 mm. It has the shape of a submersible capsule.The screwed steel back bears the engraved data of the Mariana Trench. A glass window reveals the balance of the movement. The large pointer tips and indexes filled with Superluminova make it easy to read the time even under water. The MARIANA TRENCH with its screw-in crown, strong sapphire crystal, solid case and screwed back is suitable for diving depths up to 20 ATM test pressure.

Equipment and scope of delivery:
The waterproof nylon straps in green, blue, brown and black, which are particularly popular with swimmers and divers, are soft, durable and comfortable to wear. They are provided with a KRONSEGLER emblem button and padded with water-repellent polyurethane on the underside. An extra-long pin buckle and the perforation, which is also reinforced with PU, ensure a secure fit on the wrist, in contrast to the Velcro fasteners, drawstrings and folding clasps that are often used with nylon straps. This prevents the watch from being accidently lost in the water.
The watch is delivered in an exclusive box with a certificate card, a 16-page booklet with a detailed description and a polishing cloth.
