Seagull Triple Grand Complication
In the so-called "Triple Grand Complication" combination of the tourbillon, perpetual calendar, and minute repeater functions, redesigning and repositioning the 435 parts into the limited space is as difficult as developing an entirely new complex movement. Even in the “Kingdom of Watches”, few brands are capable of this achievement. At that time, the launch of Seagull’s “tourbillon, perpetual calendar, minute repeater” wristwatch struck a chord with everyone who cared about the watchmaking industry, delighting and energizing them.
Beyond its functionalities, the "Triple Grand Complication" is no longer just a simple movement, but presents itself to the world as a high-precision and highly complex precision instrument. To ensure the accuracy of the perpetual calendar and the precision of the minute repeater, it requires the production of high-precision components, with machining accuracy reaching 0.001mm, which is one-tenth the diameter of a human hair. Some key components even achieve an unprecedented surface finish of level 13, equivalent to a mirror-like level. To produce such components, efforts were made to increase the introduction of advanced foreign equipment, while rigorous repeated experiments continuously improved process capabilities. Only through this could the precision machining techniques be progressively enhanced and improved, making modest achievements.
