My watch is ended

Keeping up with the Game of Thrones theme, as with most of our conversations these days, I recently used the epic half-liner from previous season “My watch is ended” with my wifey to remind her of:

  • The batteries of my watch have died again: even though I have been wearing wrist watches for over 20 years now, I have no idea how long are the batteries of a watch are supposed to last! Empirical evidence suggests anywhere between 6 months and 10 years, depending upon the weather conditions on Mars during that period! 
    • Side note: I can never ever wear a watch that needs charging every night! Even though I would love to, but for the foreseeable future I am not going to try any smart watch 
  • She got her first French salary (yippie!) and as per the tradition, she needs to buy me a ceremonial gift! 

For the impatient readers, Tl; Dr version of the outcome of that discussion is: after hours of research and keeping in line with my personal preference towards not charging a personal device for as long as humanly possible, we bought this beautiful piece of Fossil Mechanical watch! Just look at the video and appreciate all the intricate machinery slowly humming along inside!

For the patient ones, I did some research on types of watches and how to select a good watch. While selecting a watch is a matter of personal taste, I have documented here various types of watches available in the market so that you guys can make more informed decisions in the future: 

Types of Watches: 

Based on the “movement” (a.k.a “calibre” or the basic mechanism driving the watch and the associated functions, also referred to as ‘complications’, such as calendar, multiple time zone features etc.) a watch can be categorized into two basic categories: Quartz movement or Mechanical movement. Various manufacturers implement these movements using their own styles/techniques, but essentially these two kinds of movements are building blocks for all kinds of watches: 

How to find out if the watch is quartz or mechanical: 

Just look at the seconds’ hand! If it is making clear jumps between seconds, it is a quartz watch, if it is making a sweeping motion or several tiny jumps between seconds, it is a mechanical watch. 


Quartz Movement:

Powered by a battery, watches based on quartz movement are pretty accurate and require much less maintenance than mechanical watches. Just an occasional battery replacement and it is good to go. Typically, quartz watches are much less preferred by watch enthusiasts due to lack of craftsmanship and technology or engineering prowess in designing intricate parts. 


Simply put, the battery sends current through a quartz crystal (hence the name quartz movement). The current electrifies the crystal, which in turn vibrates. These vibrations create the movement to drive the watch motor, which in turn drive watch hands. These watches run quite accurately till the time battery is providing ample current to the crystal. As the battery starts running out of juice, you will notice that the watch has started losing time. 

Mechanical Movement: 

Powered by a wound spring, most of the luxury watches run on mechanical movement. In a lot of mechanical watches (for example in the video above), there is a provision to witness and appreciate the intricate components, working together in a tightly woven configuration to power the watch. Several super-luxury watches still have hand-crafted intricate parts, designed for a snug fit and supposed to work fine for decades. 


Mechanical movement watches store energy in a wound spring. The spring transfers energy to gears and sometimes other springs to provide regulated power to the watch hands. I am assuming your next question would be: From where does the wound spring gets its energy from? Good question! 

Types of mechanical watches: 

Manual: Remember the typical watch our grandparents wore? They were rotating the crown on the side of the watch to wind up the spring. The energy is stored in the spring and is typically enough for ~24-hour period. Though some of the newer watches may store enough energy for ~2-day period. 

Automatic: Automatic watches also have the option of rotating the crown to wind up the spring. However, they also have a metallic weight (called rotor), which is free to move when the body of the watch moves. So, when you walk or move your wrist, the metallic rotor moves, winding the spring. Hence, when you wear it daily, there is no need to wind up the spring, as it gets automatically wind up when you walk or move your hands. 

... and 

Well, that was a brief overview of different types of watches. Personally, mechanical watches interest me more, especially where the mechanism is visible through the front glass. If you are interested in the engineering behind watches you can also look at how basic gearing works in such watches and how different manufacturers add complexities (in simple terms – features) to their respective products.
