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 and its 68-hour power reserve offered by the Franco-Swiss G100 movement with 3 hands and date, the BONZER Automatic model combines style and aquatic performance.

The ceramic 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 sapphire crystal.

The brushed dial is equipped with finely serrated 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 green skeleton background reveals the G100 movement whose mass has been perforated with the 3 intersecting March LA.B lines.

The DOUBLE GREEN model is equipped with a green brushed steel dial printed with discreet light gray markings and railroad. Its sporty yet urban appearance makes it a timeless fashion accessory perfect for all everyday adventures.

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.


Franco-Swiss Automatic Movement

The first movement resulting from the partnership between the Swiss manufacture La Joux-Perret and the Bisontine family house Humbert-Droz, the G100 is a new three-hand automatic caliber with date, endowed with a fine 68-hour power reserve and a proven architecture.

This ultra-precise movement equipped with 24 jewels measuring 24.6 mm x 4.45 mm develops a frequency of 4 Hz and 28,800 vibrations.

Equipped with a Stop Second, it is extremely precise varying between - 4 and + 6 seconds per day and offers a power reserve of 68 hours more commonly called "Weekend proof" allowing the watch to operate from Friday evening to Monday morning without it being carried by its happy owner.

March LA.B positions itself as a pioneer of “watchmaking responsibility” with the desire to bring together skills and join forces for a movement 100% machined in Switzerland and 100% assembled in France.


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.
