The case
The PROFESSIONAL IV OLD RADIUM DLC model is a classic automatic diver's watch in vintage style. It impresses with its unique design and high-quality workmanship. The case has a diameter of 42.0 mm, is satin-finished and has a DLC coating. It is equipped with an anti-reflective Sapphire crystal and a Helium valve a mirror. The watch is 50 ATM pressure-tested. The unidirectional rotating diver's bezel has a black ceramic inlay.


The mechanical movement
This diver's watch is driven by an automatic movement of the company Miyota. The mechanical Movement Miyota 9015 is known for its reliability and is finely adjusted by our watchmakers before installation. The movement support ring is made of stainless steel. The Miyota 9015 movement works with 28.800 vibrations per hour, has a stop-seconds function and a date quickset.
Dial and hands
The PROFESSIONAL IV OLD RADIUM DLC model has a clearly structured black dial with line markers. The coarse structure of the dial is a striking design feature of this series. The watch is optionally available with three different date window options. The orange second hand underlines the sporty character of this automatic diver's watch.


The luminous material
The indexes and pointers are marked with Superluminova Old Radium provided. This luminous material is made in Switzerland and gives the watch its typical vintage look. The hour-markers and hands as well as the bezel shine in a subtle green tone. This ensures good readability in the dark.
Bracelet and buckle
The MARC & SONS PROFESSIONAL IV OLD RADIUM DLC model features a satin-finished five-tiered bracelet in 316L stainless steel. The solid stainless steel folding clasp has a diver extension with fine adjustment. This is easily done by pressing the lateral pushers on the buckle and extends the bracelet by up to 14.0 mm. Bracelet and buckle have a black DLC coating.


The bottom of the case
The model MARC & SONS PROFESSIONAL IV OLD RADIUM DLC has a screwed case back made of 316L stainless steel. The coarse-grained structure of the dial also extends to the back and is also a striking design feature of this series. In addition, the back has a raised symbol in the form of a diving bell.
