Overview
The Citizen Promaster Altichron BN4065-07L is a high-performance analog instrument designed for high-altitude exploration and rugged terrain. Part of the Promaster Land series, it is a "sensor-heavy" timepiece that manages to display an altimeter and an electronic compass entirely through analog hands. Housed in a massive 47mm Super Titanium™ case with a black DLC (Diamond-Like Carbon) coating, it provides extreme durability without the weight of steel. Its navy blue dial is accented with vibrant yellow and white markers, ensuring critical data remains legible during the most demanding expeditions.
Technical Specifications
Case Size: 47mm (Bold, oversized professional profile)
Case Material: Black DLC Super Titanium™ (5x harder and 40% lighter than stainless steel)
Movement: Eco-Drive (Caliber J280; light-powered with a 6-month power reserve)
Crystal Type: Spherical Sapphire Crystal (Domed for superior pressure resistance and clarity)
Water Resistance: 200 Meters (20 ATM / 666 feet) — Suitable for heavy rain, swimming, and snorkeling
Dial: Navy blue dial with multi-layered analog scales and a date window at 3 o'clock
Bezel: Fixed black ion-plated Super Titanium™
Strap: Blue high-durability nylon strap with a Super Titanium™ buckle
Special Features
Metric Altimeter: Capable of measuring altitudes from -300 meters to 10,000 meters (-1,000 to 32,000 feet). The dedicated yellow hand indicates altitude in real-time using the outer chapter ring.
Electronic Compass: By pressing the pusher at 10 o'clock, the main hands reorient to function as a compass, allowing for rapid navigational checks without needing a digital screen.
Caliber J280 "Multi-Hand" Display: This movement is unique for its ability to stack multiple hands (including a dedicated sub-altimeter hand at 9 o'clock) to show complex data while maintaining a traditional watch feel.
Super Titanium™ with DLC: The black coating isn't just for looks; the Diamond-Like Carbon finish provides a layer of surface hardness that is nearly impossible to scratch under normal field conditions.
Spherical Sapphire Crystal: The domed shape of the crystal is engineered to reduce glare and increase structural integrity against external pressure.
Power Reserve Indicator: The sub-dial at 9 o'clock serves a dual purpose, showing the current energy level when the altimeter is not in use.
Tactical Ergonomics: Features large, textured pushers on the left side of the case, specifically designed to be operated even while wearing thick climbing gloves.
Professional Lume: Features massive, high-contrast luminous markers and hands for essential time-telling in low-visibility mountain environments.
