The Gyromax is a 'free sprung' balance, meaning there is no regulator on the wheel's balance spring for adjusting the watch's rate, so the collets are used for adjusting both poise and rate. Swiss patents were granted to Patek Phillipe for the Gyromax balance on May 15, 1949 and December 31, 1951, and the balance was first used in watches in 1952.
A balance wheel, or balance, is the timekeeping device used in mechanical watches and small clocks, analogous to the pendulum in a pendulum clock.It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, known as the balance spring or hairspring.
4D Inc is a US-based subsidiary of 4D SAS and publisher of 4D.It was established in 1984 and initially led by Guy Kawasaki. [citation needed] 4D is the developer and publisher of 4D (or 4th Dimension). 4D was founded in 1984 when development began for Silver Surfer (early code-name for 4D) and had its initial product release in 1987 [1] [2] [3] with its own programming language.
The Merrill Wheel-Balancing System was the world's first electronic dynamic wheel-balancing system. It was invented in 1945 by Marcellus Merrill at the Merrill Engineering Laboratories, 2390 South Tejon Street, Englewood, Colorado , and is now recorded on the list of IEEE Milestones in electronic engineering [ 1 ] and as an American Society of ...
There are also over 100 third-party plugins, free and commercial. 4D can also be used as a web server, to run compiled database applications. Today, 4D is published by the French company 4D SAS and has a sales, distribution and support presence in most major markets, with the United States, the United Kingdom, and France being the primary ...

Balance weights are then fitted to the outer and inner flanges of the wheel. [2] Although dynamic balance is theoretically better than static balance, because both dynamic and static imbalances can be measured and corrected, its effectiveness is disputed because of the flexible nature of the rubber.
