Introducing The Citizen Eco-Drive Caliber 0100, The Most Accurate Wristwatch Ever Made

Introducing The Citizen Eco-Drive Caliber 0100, The Most Accurate Wristwatch Ever Made

Snappy Take

Last year, Citizen appeared, with shockingly little flourish, an exhibit commendable accomplishment. This was the Caliber 0100, which was introduced in a pocket watch case , as a non-creation model. In spite of the fact that it was clear from the outset that the development could without much of a stretch be utilized in a creation wristwatch, at the time there was no particular commitment from Citizen that this would occur. Be that as it may, this year at Baselworld, Citizen appeared the Caliber 0100 wristwatch, in white gold and titanium cases, making another record-holder for world’s most exact wristwatch a reality.

The new watch is housed in a 37.5mm x 9.1mm case and is being delivered as a restricted release – there will be 100 in white gold and an aggregate of 700 in Super Titanium with Duratect. Of the 700 in titanium, 200 will have a mother of pearl dial. The precision of the watch gets from its extremely high recurrence quartz oscillator, which runs at 8.4 MHz (8,388,608 Hz) rather than the 32,768 Hz recurrence of a standard quartz watch. The cut of the quartz gem is additionally unique – the type 0100 utilizations what’s called an AT-cut quartz gem, which has a capsule shape, instead of the tuning fork state of an ordinary quartz gem. Moreover, the oscillator is temperature-controlled, varieties in temperature being the absolute most huge wellspring of rate variety in quartz oscillators. 

According to Citizen, LIGA creation is utilized for components of the stuff train that drive the hands, to dispense with backfire, or play between gear teeth. Some level of play between gear teeth, anyway minute, is important for a stuff train to run yet it can bring about some imprecision in, for instance the situation of a seconds hand regarding dial markers. This way to deal with guaranteeing extraordinary accuracy in stuff commitment is ordinarily a component of better quality mechanical watches (Patek Philippe utilizes a LIGA-created wheel in the roundabout place seconds train of the new 5212A Calatrava , and Rolex utilizes one in the Daytona, as Ben Clymer announced from his Rolex production line visit article in 2015 ). The explicit way to deal with the issue of reaction in the Caliber 0100 is the utilization of a LIGA-manufactured enemy of kickback twisting spring. In contrast to ordinary quartz developments, Caliber 0100 is additionally widely jeweled, with an all out check of 17.

The single most concerning issue with high-precision, high recurrence quartz observes truly has been battery life; higher recurrence quartz oscillators utilize a ton of force and when Citizen came out with its 4.1 MHz Crystron Megaquartz in 1975, expected battery life was uniquely around a half year (as per Citizen). That watch was evaluated to an actually astonishing ±3 seconds out of every year, except the short battery life was a commercial obligation. It was nonetheless, a mind boggling accomplishment for now is the right time, and like the Caliber 0100, it utilized an AT-cut quartz precious stone. After 44 years, the energy issue’s been settled gratitude to the Caliber 0100’s utilization of sun based force, Eco-Drive innovation, which gives the watch a multi month power save (eight months in force save mode) and it’s important that this is in spite of the way that Caliber 0100 runs at about twofold the recurrence of the Crystron. (The watch will run uncertainly whenever presented to light consistently; the half year power save is the running time if the watch is kept altogether darkness).

Hands and applied lists are faceted metal (an abnormal decision for submits a watch for which limiting force utilization is an issue as they’re on the hefty side) and the watches are hand-amassed in Japan. The moderately undeniable degree of hand-work, just as the utilization of premium materials and extremely progressed mechanical and electronic timekeeping innovation, are evident signs that these won’t be 500 dollar observes however the value actually came, as far as I might be concerned, as an underlying stun. Clutch your pants, Gertrude – the titanium models are $7,400, and the white gold model is $16,800.

Introductory Thoughts

This is one of two record breaking watches delivered for the current year (the other being the new Bulgari Octo Finissimo Chronograph GMT, which is the world’s most slender selfwinding chronograph) and similarly as with every new record, it brings up the issue of when and if it will be broken. That Citizen presently has boasting rights for undeniably the most exact wristwatch at any point made, doesn’t really mean nobody else will assault that record. 

The Citizen Chronomaster

High accuracy timekeeping is a significant need at Citizen; for additional, look at our active with the Citizen Chronomaster.

AT cut quartz precious stones were created in 1938, and keeping in mind that Citizen’s Eco-Drive tech is class-driving, other enormous watchmaking companies with semiconductor limits additionally can send comparative innovation. Yet, it’s a significant attestation of thought authority with respect to Citizen to have created this watch, and to have ensured the degree of execution it gives, and however there are different firms that theoretically might have done it, the reality stays that Citizen is the company that put in the work, and did the R&D, important to make this a reality. High recurrence quartz watches are an entrancing sub-strength of watch gathering – companies as shifted as Omega, Bulova, Seiko, and Citizen itself have all created such watches, both in the present and the past; to the furthest extent that I can review the record holder for quartz precision until now was really the previously mentioned Citizen Crystron. This is with the proviso that you can improve execution from wristwatches that adjust themselves utilizing radio recurrence signals, either from earthbound transmitters or from the GPS network, yet these are not completely self-governing watches, similar to the Caliber 0100. 

Now, contingent upon things like temperature, variety in quartz precious stone execution, and different imponderables, you might just get one second a year execution out of a watch not evaluated to that exactness. I have a Citizen Eco-Drive Skyhawk that is presumably nine or ten years of age and when I previously got it I estimated its precision throughout the span of a year and it was delayed by three seconds more than 365 days. However, there is a major contrast between getting fortunate regarding execution, and having the option to guarantee performance over that long a period. The business standard practice for AT quartz gems indicates the point of deviation of the cut from the Z hub of the gem (for example) to inside 0.0042 of a degree and the point of the cut can be shifted somewhat to change the rate steadiness of the precious stone in a given temperature reach to the ideal spec. (More tight resistances will create more reliable execution, however as is typically the situation, it’s more costly.) This combined with a portion of the other specialized highlights of the Caliber 0100 make it, at any rate until further notice, actually unique.

From a down to earth point of view this is each of the somewhat unsettled, obviously – most wristwatch proprietors will not particularly notice the contrast between ±10 seconds a year, and ±1 second a year, yet this watch isn’t for most wristwatch proprietors (both regarding execution and cost). Its allure will be most grounded to the individuals who are sincerely moved by accomplishments in high exactness timekeeping. A customer for the pricey gold model, for example, may likewise have a 2.4 MHz Omega Marine Chronometer or two in their assortment, however they additionally may have high accuracy pendulum timekeepers (counting an expert slave arrangement or two) and mechanical observatory chronometer wrist and pocket watches (and indeed, I’m depicting what my own assortment would resemble in a post-Powerball win universe). Similarly as with much top of the line watchmaking, regardless of whether mechanical or high accuracy quartz, a ton of the delight of proprietorship has to do with the pride one takes in having something standout on your wrist. Greatness can be communicated in plan, put-togetherness, handwork, or in exactness execution, and in case you’re captivated by the last to any degree, the Caliber 0100 is a watch worth watching.
