A unique profile and a proud history

The uniqueness of the design of the 1970 watch stemmed largely from the way that the crown, moved to the 4 o'clock position, was protected by the extension of the case around it. The design turned out to be as memorable as it was functional and this 150 meter water resistant diver's watch rapidly found favor among those who needed a watch of exceptional strength. It was worn by the Japanese adventurer, Naomi Uemura, when he did a solo dog-sled run from Greenland to Alaska, a journey of 12,000 kilometers that took eighteen months.





Reviving the unique design completely
up-to-date in its technology

The new Prospex re-creation of this 1970 diver's watch is slightly larger than the original but faithful in every other respect to its design.
The case was given a wide, flowing design purely to protect the crown at the 4 o'clock position.
