Perhaps the most diverse of Citizens’ lineups, ProMaster never fails to surprise!
Promasterland: A Brief Introduction
Ask anyone knowledgeable about outdoor gear to recommend a wide range of watches suitable for hardcore professional athletic activities, mountain climbing and wilderness exploration; You can probably hear them cheering G-ShockThe garmin, The Seiko Prospecs And maybe even Tissot T-Touch. What most people ignore out of ignorance is a whole range of fascinating, professional wrist-top tools – the Citizen Promaster the earth, widening the range of possible activities, prove that they are both appropriate and enormous! Starting from 1989 Promaster Alticron (with a high-precision altimeter), they’re still around, only getting better over the years.
Promaster: Mastered the elements
Citizen Promaster Land: Wow!
Although there are three distinct segments introduced by the manufacturing brand, the Promaster – watches designed primarily for professional use – overlap the realms of their functional territories; sharing characteristics with each other (the sea and air) and provide comfortable properties, of which toughness and water resistance are the main ones. But again, the Promaster land The family is more capable of withstanding physical effects than the other two; A type that originates from extremely high speeds and high altitudes.
It’s not the only G-Shock that boasts a history of toughness
Citizen: The Search for Anti-Shock Measures
Looking back at the history of CITIZEN, we see them as innovators in developing more than normal tolerances for their watches, and shock resistance is just one of them. Their own proprietary anti-shock mechanism – the Preshock – for mechanical watches; It is a system that protects the most vulnerable parts of a mechanical movement, i.e. its sensitive axles Balance wheel; This, in turn, poses serious problems for the accuracy of a mechanical clock. Also, from a fall from a height of less than 6 inches. Preshock Proven effective even against a 30-meter drop; A public demonstration by citizens in 1956 proved it.
Also surprising is the fact that the predecessor to the PROMASTER series sank off Long Reef Beach, Australia for six years (1983 – 1989). Although the entire watch was covered in barnacles and algae, its self-winding mechanism worked perfectly and looked like new.
The Promaster Land series watches, without a doubt, being marvels of the modern age, have increased that toughness several flights over before; Now, we look at the mechanisms that put them in a new league of their own.
The altimeter sensor uses barometric pressure to measure depths
- An analog altimeter allows measurements from 1,000 feet to 32,000 feet.
- Three scales – hundreds, thousands and ten thousand feet
- Electronic compass dial, for taking accurate bearings during the day.
- Measures altitude for the first five minutes, then automatic readings every three minutes, for the next 12 hours
Altimeter and compass
Inspired by mechanical depth gauges, the development of microelectronics and sufficiently compact sensors allowed very accurate altimeters to be built into the watch. These sensors can detect air pressure and its fluctuations; 14.70 lbs/sq. At sea level the pressure decreases with increasing altitude, and the air becomes progressively thinner with height. However, you can also use an altimeter to track barometric pressure changes along with altitude readings.
The Alticronof The compass bezel allows users to take a basic bearing from the sun and is very helpful for mountaineers, trekkers and even off-road motoring and mountain-rallying.
Altichron was developed to enable rapid identification of critical information, establishing safety margins without delay. However, there is a big difference between the 1989 Promaster Alticron and the current one; Now they present the most significant advance in wristwatch sensor technology. It is unmatched Aqualand; A prominent bulge on the left and an LCD to display information.
Promaster Land: The Path of New Beginnings
In addition to fluctuations in atmospheric pressure, the Altichron also provides warnings of impending foul weather and allows you to estimate the time you need to return to the safety of a temporary camp or base camp.
