The BONZER is the second born surfer from March LA.B


The BONZER is the second born surfer from March LA.B.

With its rounder 41 mm stainless steel case, the BONZER Electric model combines style and aquatic performance.

The Aluminum bezel, which is thinner than on its sister, is chiseled on the rim with interlaced lines of the M of March LA.B which can be found on the crown, which is invariably placed at 4 o'clock. A positioning that avoids damaging the back of the hands during the twists necessary for the "duck". The fully brushed case for more scratch resistance is assembled with a raised and domed mineral glass.

The brushed dial is equipped with baton indexes. The counter surrounded by a chiseled steel window features a date stamp with very retro white numerals printed on a black background, revealing the number 3 in green once a month.

On the back of the watch, the screwed back in brushed steel is engraved with the emblem of March LA.B.

The OCEAN model is fitted with a blue sunray dial in steel and printed with discreet light gray markings and railroad tracks.

The BONZER is a watch for everyday athletes.

March LA.B designs and assembles its watches in France. The Swiss automatic movements that we fit into our timepieces are assembled from A to Z in France. In complete transparency, we are thus pursuing our watchmaking quest to design watches that are “as French as possible”.


The 20 mm colored silicone straps are equipped with the "presto" system allowing them to be interchanged in a few seconds and without special tools.
The steel bracelets equipped with the same "presto" system are an assembly of 3 links that we have "reshaped" by adding micro cells to the back for better comfort when worn.

The BONZER Model

The BONZER comes to enlarge the range of our "Surfer girls". It takes its name from the revolutionary surfboards shaped by the Duncan brothers and Malcom Campbell in the 70s. Faster, more maneuverable and more aggressive boards, easy to surf and suitable for all types of waves. Our BONZER will also adapt to your everyday life. We “Shaped” it in a 41 mm round case with controlled thickness and fitted with a notched rotating bezel and a screw-down crown for perfect water resistance. In the steel or silicone bracelet version, it will be ideal for spending your life in the water... In the more refined leather version, it will be perfect for "chilling" in the office. Ondine or city-dweller, the BONZER is on time.


Swiss Quartz Movement

Distinguished by its precision and reliability, the Swiss quartz caliber RONDA 517 proves to be the best choice for many luxury watch brands due to its very high quality performance.

This Swiss movement is equipped with a quartz oscillator that uses electrical vibrations to maintain remarkably high time accuracy. It is also equipped with a temperature regulation system, which allows the frequency of movement to be adjusted according to thermal fluctuations, thus guaranteeing constant precision whatever the ambient conditions.

In addition to its precision, it is also designed to be extremely reliable and durable. It features a long-life power supply system that enables battery life of up to 60 months. About 2 weeks before the end of battery life, an indicator called EOL causes the second hand to jump (seconds hand) every 4 seconds to signal the need to change the battery.


March LA.B's "Green Thread" is an omnipresent green signature through subtle details. The number 3 in green on the personalized date stamp recalling the favorite month of the founders of the brand. The green lining of the bracelets topstitched with a bridle stitch in the emblematic green color. The luminous green “skeleton” background on the automatic versions.
The interior of the emerald green travel case…

This "Green Thread" extends this "design grammar" that we have developed in order to identify our timepieces through precise and redundant aesthetic codes: The crown or winder at 4 o'clock and its guillochage of the intertwined lines of the M of the brand, the seventies typography of the date stamp, the dials without numbers with cut-out indexes, the raised and domed glass, the ubiquitous angles on the cases that are always polished and brushed.

All of these aesthetic and chromatic details to be discovered in intimacy shape the common thread of March LA.B which leads straight to the heart.
