The BONZER is the second March LA.B “surfer” watch.


With its rounder 41 mm 100 meters waterproof stainless steel case the BONZER Electric model combines style and aquatic performances.

The aluminum bezel, thinner than its sister is chiseled on the rim with the March LA.B interlaced M lines as on the screwed crown always located at 4 o'clock. A position that avoids damaging the hands back while twisting them for the "duck dive". The fully brushed case is more scratch resistant and assembled with a raised and domed mineral crystal.

The brushed or sunray dial are built with clean indexes

The stamped date is surrounded by a metal window frame.
The very retro white digits are printed on a black background that displays the number 3 in green once a month.
The week day can be displayed in french or English.

The brushed screwed back is engraved with the March LA.B horological crest.

The OCEAN model is made of a blue sunray dial printed with discreet light gray markings and railroad inserted in a steel case with a black aluminum bezel.

The BONZER drops in to complement our Surfing range. A name inspired by the revolutionary surfboards shaped by brothers Duncan and Malcolm Campbell in the Seventies. Faster, more maneuverable and more aggressive surfboards, easier to ride and ideal in every wave. Our BONZER will also adapt to your everyday lifestyle. We shaped it in a circular 41 mm case, containing its thickness and fitting a rotational notched bezel and a screwed in crown for seamless waterproofing. In a stainless steel or silicone band, it will be perfect to enjoy life underwater... In a more refined leather strap, it will ideal to chill at the office. Marine or metropolitan, it is BONZER o’clock.


Well-known for its accuracy and reliability, the RONDA 517 Swiss quartz caliber has been selected as the best choice for many luxury watch brands due to its very high-end performances.

This Swiss movement assembled with a quartz oscillator uses electrical vibrations to keep a very high time accuracy. With the temperature regulation system allowing the movement frequency to be adjusted according to thermal fluctuations, a constant precision whatever the ambient conditions is guaranteed.

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 around 60 months battery life. About 2 weeks before the battery end of life, an indicator called EOL makes the second hand jumping every 4 seconds to tell that battery needs to be changed.


Le « Fil Vert » de March LA.B est une signature verte omniprésente au travers de subtils détails. Le chiffre 3 en vert du dateur personnalisé rappelant le mois fétiche des fondateurs de la marque. La doublure verte des bracelets surpiquée d’un point de bride de la couleur verte emblématique. Le fond « squelette » d’un vert lumineux sur les versions automatiques.
L’intérieur de l’écrin de voyage vert émeraude…


Ce « Fil Vert » prolonge cette « grammaire du design » que nous avons développée afin d’identifier nos garde-temps au travers de codes esthétiques précis et redondants : La couronne ou remontoir à 4 heures et son guillochage des lignes entrelacées du M de la marque, la typographie seventies du dateur, les cadrans sans chiffres aux index découpés, le verre réhaussé et bombé, les angles omniprésents sur des boitiers toujours poli brossés.


L’ensemble de ces détails esthétiques et chromatiques à découvrir dans l’intimité façonnent le fil conducteur de March LA.B qui mène droit au cœur.
