Citizen Pocket Watch: A Hidden Gem with The Calibre 0100

A precise light-powered movement in a classic timepiece, the Citizen pocket watch with the Calibre 0100 is the distinguished timepiece.
Mar 26, 2024

Ibelieve that pocket watches aren’t something highly admired by the youth anymore. Some might still be keen to include them in a collection but many people have been spoiled with choices for modern wristwatches. Yet, pocket watches are still in the market meaning that they rest in a special place for its enthusiast. Therefore, in this article, I’m going to show you an advanced piece of Citizen pocket watch that would enchant you.

Pocket watches do indeed old and tend to be the trend of early age. Yet, many agree that pocket watches have a persona that would never be found in modern timepieces. Citizen is one of the leading Japanese watch brands that has also been in the game of pocket watches. Even their journey started with a pocket watch released in 1924. 

During the Baselworld’s exhibition in 2018, Citizen unveiled its special pocket watch as a homage to its first one. Not only that it comes in a clear and crisp dial but the engine behind its dial is the main surprise. It is powered by the Caliber 0100 that offered super-accurate time telling. 

As a note and disclaimer, that technology is wrapped within a pocket watch case as a commemoration of their first journey marking the centenary of the Citizen company. The pocket watch is a prototype that wasn’t for sale but the movement would be applied to other models.

Yet, the idea of choosing a pocket watch to introduce Citizen’s latest technology is still an endearing choice, I personally think. It means that pocket watches still hold an important value.

Citizen Pocket Watch: Calibre 0100

Below, I’ll talk about Citizen pocket watches and the technology of Caliber 0100 would be the main subject. Let’s dig in!

The Caliber 0100 itself is actually part of the Eco-Drive movement — a benchmark of the Citizen watch company. Introduced to be the most precise one, it offers an unmatched accuracy of ±1 second in one year. While the common quartz watches are mostly accurate to +/-1 second per day, the Caliber 0100 is an exceptional technology that put many in awe.

As a solar-powered watch, this Citizen pocket watch is also an excellent timepiece for its classic design. It might look old considering its type but at the heart of it is the most reliable watch movement ever.  

Citizen also highlights the power reserve that can last for up to 6 months in total darkness without charging. However, I also thought that having a solar-powered pocket watch is quite a hassle as people mostly keep the watch inside their pocket — meaning that it’s not exposed to light.

Such a situation might decrease the watch’s performance as it can’t store energy. But thanks to the ability to keep running until 6 months, this Citizen pocket watch wouldn’t be as problematic as I thought.

In detail, the Caliber 0100 runs at the frequency of 8.4 Mhz which is lots faster than the Omega Marine Chronometer from the 1970s. The name is also referred to as the 100th Anniversary of Citizen watch company to serve watch aficionados collections of great timepieces. 

In addition to that, the cut of the crystal is also something crucial to talk to. Instead of using a common tuning fork configuration, Citizen decides to use an AT-cut crystal. The AT-cut is a wise choice to reduce the effects of extreme changes in temperatures that affect accuracy. In quartz watches, most inaccuracy is caused by quartz oscillators but the use of AT-cut helps to lessen the vibrations.

The AT-cut would do a continuous monitor and adjust the temperature changes to maintain accuracy. Not only that, but Citizen also equips the movement with a great shock resistance and features to automatically correct watch positioning for better reliability of accuracy.  

The appearance of this special Citizen pocket watch is also a captivating view to look at. The clear white on the dial gives a classic and elegant look for a timepiece that is mostly kept inside the pocket. The case is made of sapphire crystal for an endearing elegance.

As for the case back, it is designed with an exhibition style using sapphire glass, allowing the wearer to enjoy the working Caliber 0100. Frankly speaking, I would love to have it as a pocket watch to hold the value and meaning behind the choice.

The citizen pocket watch with the Caliber 0100 might only be a prototype for the technology. Yet, celebrating a special event using a pocket watch as a homage to Citizen’s first model gives an idea of how significant this classic timepiece is. Who knows that we can look forward to the availability of Citizen pocket watches that hold modern technology.
