A built-in “fully automatic perpetual calendar” that requires no adjustment up to the year 2100.
There is no need to wind it manually when the month has fewer than 31 days, and for leap years an extra day is automatically added. Driven by an ultrasonic motor, it uses IC signals to ensure highly accurate time displays. This watch also incorporates the most advanced technology of the times, including features such as a lithium battery lasting 10 years.
The crown and the bracelet give it real character.
To enlarge the date and make it easier to read, it has a shell-shaped specialty magnifying lens built into the glass of the body. This watch is proud of its high accuracy, and features a crown which is ordinarily rarely used and which is designed to fit right into the case. And by making the first link of the bracelet slightly longer, the case and the bracelet feel more closely integrated. This is a watch with distinctive features that have been carefully coordinated with an overall master design.
