Unearthing the Magic of Mechanism: A Dive into the Marvelous Ways Mechanical Watches Wind

Published: 16 Nov 2025
The beautiful symphony created by moving parts in a mechanical watch is truly enchanting. But have you ever wondered how these mechanical timepieces are wound? Let's find out.

There exists a fascinating array of watch movements, primarily divided into two categories: quartz and mechanical. Quartz watches rely on a combination of battery power or solar energy, with mechanical timepieces operating via mainsprings, devoid of any electrical inputs. Despites these major divisions, the watch world is also populated by unique exceptions such as Seiko’s Spring Drive or Accutron’s Electrostatic caliber. Diving deeper into the realm of mechanical movements, one can discover finely-tuned mechanisms that are wound either by hand or automatically. These motions offer a multitude of winding methods, often leading into a captivating journey of mechanical marvels.
Perhaps the most familiar method of winding any mechanical watch is through the crown, traditionally positioned at 3 o’clock. However, other placements, such as 2, 4, 12, or even 9 o’clock aren’t uncommon. Well-known automatic movements such as Seiko’s 7S26, fascinatingly, do not rely on the crown for winding but instead use the spinning action of the rotor. The crown is connected via the stem to a winding pinion, engaging with the mainspring barrel via a ratchet wheel. This complex arrangement results in the coiling and tightening of the mainspring within a barrel, simultaneously increasing the power reserve. In the earlier days, pocket watches were equipped with a separate winding key, but modern designs have shifted towards the integration of what is known as the keyless work mechanism. Providing the crown with its multifunctionality(winding, date setting, and time setting), this mechanism lays the backbone of modern horological marvels. Akin to a magical rhythm, unaffected by the sands of time, the winding of a mechanical watch continues to enthrall enthusiasts all over the globe, rendering it an art in its own right.
