Expanding their line of Star Trek wristwatches first introduced in January, design house Vannen this week is adding two new color variants of their USS Enterprise watches this month.

Initially launched in white and grey back in January, Vannen this month has added a pair of new color themes to their lineup, rendering the USS Enterprise-themed design from artist Tom Whalen into a black-and-electric-blue and a white-and-matte-clear look.

The two new, special edition Enterprise variants are limited to 150 pieces each, and include color-themed silkscreen art on the straps, dial, and crystal, along with Star Trek branding on the rear casing and even a tiny Starfleet delta on the crown.

The design is based upon Whalen’s artwork for the 50 Artists, 50 Years collection released in 2016, featured upon the cover of the hardcover reprint book.

Each watch retails for $65.00, and is available until the 150-piece run sells out at Vannen’s website.
