Embark on a horological journey inspecting the wonders of the Miyota 9075 Calibre, and understanding the marvels of the True GMT functionality.

Not long ago, a deep investigation into a series of Miyota automatic movements was undertaken, the ubiquitous Calibre 9015 being among them. These explorations aimed to dissect the intricate parts of these models, understanding the construction, and appreciating the aesthetic appeal hidden under the case. This journey of discovery proved to be full of surprises, with the remarkable precision and attention to detail concealed within the timepiece being particularly arresting.

In the wide spectrum of watchmaking, the distinguished Japanese firm Miyota stands boldly. The titan watchmaker has, for more than four decades, produced an eye-watering five billion movement units, asserting itself as one of the dominant forces within the horology world. Within their extensive portfolio, the Miyota Calibre 9075 holds a distinguished position, thanks to its True GMT functionality.

Miyota’s prowess as a large-scale industrial watch producer is universally acknowledged. Its watches – akin to those from other industry giants like Casio, Seiko, and Citizen – are known for their reliability, attainable costs, and high production volume, making them the starting point for many collectors.

From classic three-handers to skeletonised and even chronograph movements (quartz only), Miyota’s range is impressively diverse. However, it’s the affordability and reliability of the Calibre 9075 with its True GMT function that makes it a game-changer in the sub-£2k market.
