NOMOS Glashütte Tangomat Date – Ref. 602

The NOMOS Glashütte Tangomat Date ref. 602 combines the clean, Bauhaus-inspired design language of the Tangente with the convenience of an automatic manufacture movement and patented date mechanism. Slightly larger and more substantial than the classic Tangente, the Tangomat retains the characteristic minimalist aesthetic while offering greater wrist presence and everyday practicality.

Case

Crafted in stainless steel, the case measures 38.3 mm in diameter and approximately 8.3 mm in thickness, with a 48 mm lug-to-lug measurement. The characteristic straight lugs and narrow bezel give the watch its unmistakable NOMOS profile.

The watch is fitted with a sapphire crystal and sapphire display caseback, allowing the beautifully finished movement to remain visible.

Dial

The galvanized white silver-plated dial features the characteristic NOMOS combination of Arabic numerals and baton hour markers, complemented by elegant tempered blue steel hands.

A recessed small-seconds display at 6 o’clock is accompanied by the distinctive large date aperture, providing useful everyday functionality while maintaining the clean and balanced appearance of the Tangomat.

Movement

This earlier example is powered by the automatic NOMOS manufacture calibre Zeta (ζ), as confirmed by the movement visible through the caseback. The Zeta is an in-house automatic movement featuring NOMOS’s patented date mechanism, stop-seconds and a bidirectional winding rotor.

The movement measures 31 mm in diameter and 4.3 mm in height, contains 26 jewels, and provides approximately 42 hours of power reserve. Traditional Glashütte construction and finishing include a three-quarter plate, Glashütte stopwork, tempered blue screws, Glashütte ribbing, NOMOS perlage and sunburst decoration. NOMOS also specifies that the Zeta was adjusted in six positions.

The current version of ref. 602 uses the later DUW 5101, but the movement photograph confirms that this particular watch belongs to the earlier Zeta-equipped generation. NOMOS’s own calibre archive also specifically lists the Tangomat Date ref. 602 among watches fitted with Zeta.

Bracelet / Strap

Original NOMOS black leather strap with original NOMOS stainless steel pin buckle. The watch has a 20 mm lug width.

Condition

Good overall condition with noticiable signs of wear on the case back. No service history available.
