Just 65 grams of indestructible Japanese engineering. The BN0247-01L is the pure embodiment of Mont-Bell's “Function is Beauty” philosophy. With a monoblock case made of hardened Super Titanium™ (Duratect MRK) and a deep blue dial with high readability, this watch eliminates all superfluous elements. It is a Limited Edition of 750 pieces worldwide and comes with two straps: brown leather for everyday adventure and black rubber for total immersion. Forget you're wearing a watch until you need it.

🪶 Featherweight (65g): By dispensing with the metal bracelet, this watch weighs almost half as much as its “All-Black” sibling. It's so light that it disappears on your wrist, ideal for climbing or hiking where every gram counts.

🛡️ Armored Monoblock Case: It has no back cover. The movement is inserted from the front, creating a sealed titanium block with no structural weak points. Total protection against dust, water, and mud.

Dual Personality Kit: Comes standard with a brown calfskin strap (classic field aesthetic) and an additional black silicone strap (for water and sweat). Change your look in seconds.

💎 Duratect MRK (Silver): Titanium is not just “titanium.” It is treated with a hardening gas (MRK) that penetrates the metal, making it resistant to deep impacts, not just superficial scratches.

☀️ Eco-Drive E168: Citizen's inexhaustible motor. It charges with light and has a 6-month power reserve. Absolute reliability in remote locations.

This file is slightly different from the previous one because this model (BN0247-01L) is not the “Tactical Black” version, but the “Heritage/Explorer” version with a blue dial and silver titanium case.

It is a more classic and versatile piece, but just as technically impressive. Here is the optimized spec sheet highlighting its extreme lightness (it is almost half the weight of the previous model) and its versatile straps.

Unlike the “Full Black” (DLC) model, which seeks a tactical aesthetic, the BN0247-01L is a tribute to the classic Field Watch for exploration.

What makes this reference special is the use of Duratect MRK on bare titanium. While standard TIC coating only protects the surface, the MRK (gas hardening) process changes the molecular structure of the top layer of titanium. It is the same finish used by the brand's 1000m professional divers.

The monobloc case is a purist detail: by eliminating the rear screw, you eliminate an O-ring and a point of moisture entry. Together with the sapphire crystal and the E168 caliber, you have a “watch for the end of the world” that you can wear with a suit (with the leather strap) or while kayaking down a rapid (with the rubber strap).
