Leaving aside the automatic 'True' GMT movement supplied pre-assembled from MIYOTA® Japan (Citizen® Movement Division), each unit of the OX® FROG300 is meticulously assembled by skilled technicians in Shenzhen, from where they are shipped worldwide once completed. In Shenzhen, the production and quality team, including the founder of the company, oversee and ensure that each manufactured unit surpasses any required quality standard, from component manufacturing, assembly, water resistance testing, timekeeping verification, packaging, to the final shipment of each unit.
NOTE THAT: Shenzhen is a China region known for housing the best consumer-to-quasy luxury watchmaking in the world (and we say world because many major European, Japanese, and American brands produce partially or entirely here). And, in Shenzhen we find latest technology manufacturers, like Huawei or Tencent (Apple manufacturer) too.
