Today, Nomos Glashütte announced that they will be launching a new themed set of watches within their square-shaped Tetra collection at Baselworld 2014 next month. The Tetra Berlin collection will come in four new dial colors: bold turquoise (lacquered), auspicious gold (galvanized), baize green (lacquered) and midnight blue (lacquered).

All models come with gold-plated hands and are fitted with a grey velour strap. Three of the Tetra models are equipped with hand wound NOMOS Alpha calibers. The Kleene model, however, has a power reserve indicator, and so it is powered by caliber DUW 4301.

The mirror polished case is perfectly square and measures 29.5 mm by 29.5 mm. It is just 6.3 mm in thick. Printed numerals and indexes mark the hours, along with a printed minute track. A small seconds display sits at 6 o’clock. A sapphire crystal protects the dial, and there is also a clear case back. Water-resistance is 30 meters.
