The Delta Type

lume mode

The Delta Type completes the cherished GMT watch by building on today's foremost GMT movement - the Sellita SW-330. The patented PAN-GMT display offers hands, indices, and a color-scale that simultaneously indicate time in any two timezones on Earth, including regions with 30 or 45 minute offsets to GMT.

The Delta Type is priced at $2450 and will be a limited edition series of 300.

Production note: The watches shown in current photography display "Patent Pending" on the caseback. The final production models will be engraved "Patented."
