Miyota 9075 movement: an automatic caliber with GMT complication

Miyota is a Japanese company specializing in the manufacture of watch movements. Founded in 1959, Miyota is known for its high-quality movements and reliability. Miyota movements are used by many watch brands around the world: they are renowned for their precision, durability and also for their value for money. The Japanese manufacturer offers a wide range of movements ranging from traditional mechanical movements to quartz movements, all with more or less high finishes.

Explanation of the GMT functionality on a watch !

Let us introduce you to the GMT functionality before talking about the Miyota Caliber 9075 GMT.

The GMT or Greenwich Mean Time feature allows you to read the time in two different time zones on the same watch. This can be very useful for people who travel a lot or who are used to staying in another country for a while. In most cases, GMT watches have an additional hand (the red hand in the photo below) that indicates a second time zone and this hand most often rotates on a 24-hour cycle.

The second time indication (GMT time) is generally read on an internal or external bezel graduated over 24 hours as on the famous GMT Master II from the Rolex watchmaking house. This is the simplest system for viewing the time in two different time zones at a glance. It is even possible with a subtle adjustment of the bezel and the GMT hand to have up to 3 time zones!

Introducing the Miyota 9075 GMT Movement

The Miyota 9075 GMT movement produced by the Miyota manufacturer is particularly prized for its GMT (Greenwich Mean Time) function, allowing the display of two time zones simultaneously.

As an automatic movement, the Miyota 9075 GMT winds itself automatically with the movements of your wrist. This feature partially eliminates the need to wind it manually, providing a convenient and stress-free user experience.

Reliability, precision and finishing are major aspects of this movement. Miyota is renowned for producing robust and precise movements, ensuring consistent and reliable performance over time.

Some watches that run on the Miyota 9075 GMT movement

The Miyota 9075 GMT movement is used by many watch brands, for example:

The LIP Nautic Ski GMT. This is one of the most iconic models of the LIP brand which features a Miyota 9075 GMT movement which is a diving watch initially unveiled in 1967 for the brand's 100th anniversary.

The Bulova Classic Wilton GMT. This American brand is well known for its Aventura watch and its tuning forks. Here we find a smart GMT, in a style opposite to the LIP Nautic that we have just discussed.

The Miyota 9075 GMT movement in our Paul collection!

At Gustave & Cie we have also chosen to use this Japanese caliber in our latest automatic watch collection, the Paul 24h collection.

For our new watch we wanted to offer a 24-hour display where the single hand goes around the dial in one day. We therefore use only the GMT hand of the Miyota 9075 movement in order to obtain this very special display, a pillar of our DNA and our watchmaking house.

This Japanese movement also allows us to offer a reliable and affordable watch entirely assembled in our workshops in Besançon.
In conclusion, we chose the 9075 GMT caliber on the one hand for its GMT function, on the other hand for its quality and price but also because it is a robust movement which requires very little maintenance.

So now, come to our boutique in Paris or to our website to find your ideal watch.
