The first movement resulting from the partnership between the Swiss manufacturer La Joux-Perret and the Besançon-based family business Humbert-Droz, the G100 is a new automatic three-hand caliber with date, boasting a generous 68-hour power reserve and a proven architecture.
This ultra-precise movement, equipped with 24 jewels and measuring 24.6 mm x 4.45 mm, develops a frequency of 4 Hz and 28,800 alternations.
Equipped with a Stop Seconds function, it is extremely precise, varying between -4 and +6 seconds per day, and offers a 68-hour power reserve, more commonly known as "Weekend proof," allowing the watch to run from Friday evening to Monday morning without being worn by its lucky owner.
March LA.B positions itself as a pioneer of "responsible watchmaking" with the desire to bring together skills and unite forces for a movement 100% machined in Switzerland and 100% assembled in France.
The dial of the AM89 Automatic is built with the typical 70s "cross hair" design. It is deliberately simplified and assembled with fine, elegant hour markers.
The steel date window positioned at 3 o'clock displays retro-font numbers in white on a black background, and in green on the 3rd of each month. A subtle printed minute track frames the dial.
The M logo is a finely cut appliqué.
The hands are thin to allow the whole to breathe.
Luminova is applied above each hour marker and on the face of the hands.
All March LA.B watch cases meet scrupulously respected construction criteria. Invariably polished and brushed, they capture ambient light to bring your watch to life.
The AM89 is a beautiful round case, 13.2 mm thick and 38 mm in diameter, with angular, streamlined lugs that reveal a slight flat surface all around the immaculate polished bezel.
The contrast of its lines makes it a modern watch, slightly vintage yet contemporary at the same time.
The anti-reflective, almost scratch-proof sapphire crystal, slightly raised, is angled to reaffirm the character of this more classic watch.
The round crown, placed at 4 o'clock, has been simplified and reduced for greater elegance and simplicity.
