AM2 AUTOMATIC Ultimate Watch
The first movement born of the partnership between the Swiss manufacture La Joux-Perret and the Besançon family firm Humbert-Droz, the G100 is a new three-hand automatic calibre with date, offering a generous 68-hour power reserve and a proven architecture.
This ultra-precise movement, with 24 jewels and measuring 24.6 mm x 4.45 mm, beats at 4 Hz (28,800 vibrations per hour).
Fitted with a hacking seconds function, it is extremely precise, varying between -4 and +6 seconds per day, and offers a 68-hour power reserve, 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”, bringing skills and forces together for a movement 100% machined in Switzerland and 100% assembled in France.
This “Ultimate” version features a screw-down crown. Combined with our double-gasket system, this extra security guarantees water resistance in all circumstances.
The black DLC case of the AM2 and AM2 Slim is radically streamlined. The flanks are sharp and angular, and the crown at 4 o’clock is deliberately set into a “recess” in the case middle.
The lacquered MARCH LA.B M logo completes a round crown chiselled with the MARCH LA.B interlaced lines.
The AM2 features an anti-reflective sapphire crystal, virtually scratch-proof and slightly domed for a guaranteed 70s effect.
The AM2 Ultimate case is coated with a deep black, ultra-resistant DLC (Diamond-Like Carbon) treatment.
The new black dial of the AM2 and AM2 Slim Ultimate is guilloché with the signature interlaced lines of the MARCH LA.B logo.
Built on two different levels, it features solid cut-out indexes positioned horizontally at 11, 1, 5 and 7 o’clock.
A discreet printed railway track frames the whole. The steel date window at 6 o’clock reveals retro-style numerals in white on black, and in green on the 3rd of each month.
The M logo is a finely cut applique.
The tuning-fork hands frame optimal readability.
