Miyota 9075 Automatic GMT Movement: Japanese Precision for Modern Travelers
In the world of contemporary watchmaking, the search for the perfect balance between reliability, functionality, and accessibility has become central.
More and more enthusiasts are seeking advanced mechanical movements capable of offering useful complications in everyday life without sacrificing robustness and precision.
It is in this context that Bramier chose to adopt the Miyota 9075 automatic movement, a Japanese caliber that has won over collectors and travelers thanks to a distinctive feature: the "true traveler" GMT function.
In this article, we'll explore in detail what the Miyota 9075 is, how it works, and why it's an ideal choice for a Bramier watch.
Introduction to Automatic GMT Movements
Before delving into the specifications of the Miyota 9075, it's helpful to clarify what a GMT movement is.
A GMT (Greenwich Mean Time) movement allows you to display two time zones simultaneously, generally via a dedicated fourth hand.
There are two main types of GMT:
Caller GMT, where the GMT hand is adjusted independently
True or Traveler GMT, where the local time hand is adjusted independently
The Miyota 9075 belongs to the second category, the most sought-after by enthusiasts and traditionally reserved for higher-end movements.
What is the Miyota 9075 movement?
The Miyota 9075 is an automatic mechanical GMT movement produced by Miyota, a Japanese company part of the Citizen Group, known for the high quality and reliability of its calibers.
It is a movement:
Automatic
With GMT function with independent local time adjustment
Designed for practical, everyday use
This combination makes the 9075 one of the most interesting GMT movements in its category.
Main Technical Features of the Miyota 9075
The Miyota 9075 stands out for its solid and balanced specifications:
Frequency: 28,800 vibrations per hour (4 Hz)
Jewels: 24
Power Reserve: Approximately 42 hours
GMT Function: Local time hand adjustable in one-hour increments
Wind: Automatic with manual winding option

The "jump" local time adjustment allows you to change time zones without stopping the watch, maintaining its accuracy.
Advantages of the Miyota 9075 Movement
"True Traveler" GMT Function
The main strength of the Miyota 9075 is the independent management of the local time hand.
This feature is particularly appreciated by frequent travelers, as it allows them to quickly and intuitively adjust the watch to a new time zone.
Japanese Reliability
Miyota is synonymous with robustness and durability. The 9075 is designed to withstand daily use and ensure consistent performance.
High Frequency
The frequency of 28,800 A/h ensures a smooth sweep of the seconds hand and good chronometric stability.

Potential Limitations of the Miyota 9075
Like any movement, the Miyota 9075 also has some compromises:
Essential Decorations: The movement's aesthetics are functional, not designed for particularly elaborate casebacks.
Chronometric Performance: While precise, it is not COSC-certified.
These limitations are minor when compared to the extraordinary GMT functionality it offers.
