We take trades against any of our watches!!! We also buy watch packages!!

The SEA-AIR-LAND adventure started in 2005 with a special order for watches for police officers belonging to RAID, the special French police enforcement unit. These watches were expertly crafted to meet the needs of these security professionals. The originality of their design has enabled them to fulfil every requirement of the members of the French Special Forces. MER-AIR-TERRE have proved their worth in action in the activities of the various military units deployed in the French army’s many theatres of operation.

MER-AIR-TERRE is one of the very few and one of the last independent French watchmakers firmly rooted in family values that puts the emphasis on reliable operation in day-to-day use. The firm of MER-AIR-TERRE has always upheld the traditions of French watch-making, right from the outset.

This French brand was founded in 2007. Since then it has grown to have not only its own manufacturing workshop, but also an R&D department, a quality control unit, an after sales department, a showroom, and also its own Marketing & Communication department. The workshop, located in the Rue Vignon, close to the Madeleine Church in Paris, is devoted entirely to the assembly, quality control, maintenance and repair of MER-AIR-TERRE brand watches. These facilities mean that MER-AIR-TERRE can design and manufacture its products fast and flexibly. We have our own design team who design the various models making up our current collection.

Day by day, our watch-making firm benefits from the experience and know-how of many serving security professionals. Their ideas and their advice help us create reliable and robust timepieces for specialist units and Special Forces. Our watches are respected and admired by collectors and watch enthusiasts alike.

Our models spring from one of the three elements – sea, air and land. MER-AIR-TERRE actually means ‘Sea’, ‘Air’ and ‘Land’ in French. The combination of functionality, quality and understatement has won the loyalty of a large section of the special unit and collector market. They find that MER-AIR-TERRE are the best timepieces for them.

MER-AIR-TERRE is a brand aimed at everyone who loves sport, adventures or beautiful objects, and who wants to step off the beaten track to find a watch of unique character. 

Passion and precision, know-how and excellence, esprit de corps and self-discipline – these are the values they share with the world of watch-making. That is why we have such strong ties with the most prestigious military units.

Several direct intervention units and teams have been so impressed by the superb performance, very reasonable price, robustness and easy-to-read dials of these automatic mechanical instruments that they decided they too wanted these watches.

These include the French special operations command and control centre, the Paris Fire Brigade, and the mine clearance unit. They have since ordered these instruments, adding special features to meet the specific requirements of their particular field of work.

SEA-AIR-LAND specialises in military watches. It has won the respect of all security professionals and watch enthusiasts. Its timepieces have three fundamental properties that set them apart: they are RUGGED, their dials are EASY TO READ and they are UNDERSTATED in style. 

Since its foundation, MER-AIR-TERRE has forged close links with the special forces of various armies, particularly since 2005 when the AG1-RAID watch first went into production. It was the forerunner of the range, and has since become a brand icon. So, to celebrate the 30th birthday of RAID, the French elite police enforcement unit, and also its own first 10 years of existence, MER-AIR-TERRE once again produced a limited edition chronograph, restricted to 150 units, each with its own individual sequential number. These watches are the embodiment of the immutable values that these men raise to a peak of perfection, values of which the superb features of MER-AIR-TERRE products are the hallmark.

In 2013, MER-AIR-TERRE worked closely with the French Foreign Legion to mark the 150th anniversary of the Battle of Camarón. These watches, produced specially for the famous Foreign Legion, are authentic because these timepieces respect the cultural, technical and aesthetic codes that govern the work of legionnaires daily throughout their lives.

Also back in 2015, MER-AIR-TERRE got together with the pilots of the US Naval Force to design an automatic watch with an additional mechanical complexity: a second time zone. This feature is also much appreciated by travellers and globetrotting adventurers.

So our firm is founded on the work of the members of the Special Forces who wear these instruments on their wrists. These timepieces are the outcome of exclusive projects run for the benefit of and in cooperation with specialist units – the RAID special police enforcement unit, the French Foreign Legion, and the US Naval Aviation.

This is one outstanding timepiece!
