360° protection system technology•
Modello Quattro undergoes full reconstruction to accomodate the new antishock technology, transforming it into the ultimate tool watch, while still remaining a benchmark of reliability and utilitarian simplicity. Thanks to the Seiko VH31 quartz movement that has been nested in the in-house designed 360° protection system and with its 300 m water resistance, the Modello Quattro tough combines the best of both dive and field watch attributes.
Its custom construction, composed of a 360° protection shell that perfectly holds the movement and a dial top protective ring, allows the watch to withstand extreme environmental stress while still keeping it super light.
U.S. MIL-STD-810 is a United States Military Standard that emphasises tailoring an equipment’s environmental design and test limits to the conditions that it will experience throughout its service life, and establishing chamber test methods that replicate the effects of environments on the equipment rather than imitating the environments themselves.
Verifying the capability of the UT4 (Unit under test) to withstand the shock due to an accidental fall in an urban environment. The drop test was performed according to the parameters reported in the reference standard:
Height – 1,22 m
Impact surface – Industrial concrete
Drops – 26 (one for each surface, corner and edge)
Units under test – 5
After the impacts, all the 5 units under test were functioning. More thorough functional and integrity checks were performed, and no malfunctioning or damage was found in any of the units.
