Citizen Promaster Altichron Super Titanium 47 mm Blue Dial Nylon Strap [BN4065-07L]

The Citizen Promaster Altichron BN4065-07L brings outdoor measurement functions to a distinctive analogue watch. Its substantial 47 mm Super Titanium case combines lightweight construction with a black DLC coating, while the navy blue dial uses bright markers and yellow accents to distinguish its displays. Luminous hands and markers support readability in dim conditions, and a spherical sapphire crystal adds depth to the dial. A nylon strap completes the practical design, giving this Promaster a relaxed character suited to active days and weekend exploration.

Citizen’s Eco-Drive Calibre J280 draws energy from natural and artificial light, providing approximately eleven months of operation on a full charge. The pressure-based altimeter displays elevations from 300 metres below sea level to 10,000 metres above it, while an electronic compass provides a directional reference. Both functions allow calibration, helping account for local conditions. These supplementary tools sit alongside everyday time and date displays, with a power reserve indicator keeping the remaining charge in view. For enthusiasts who enjoy traditional hands and scales, the Altichron offers an engaging way to follow changes in elevation and direction.
