Mühle-Glashütte Lunova watches

The Mühle-Glashütte Lunova is a 42.3 mm automatic watch from Glashütte. The name joins two Latin words, lumen (shine, light, glow) and novus (new, fresh, young), which Mühle renders as "new shine". The Lunova keeps the brand's nautical virtues of precision, robustness and legibility, but its case is unusual for Mühle: many of its surfaces are polished, and on the Lunova Date they are polished all over.

The versions share the 42.3 mm diameter, a screw-down crown, an anti-reflective sapphire crystal, an exhibition back and 10 bar water resistance. They differ by movement, and with it by thickness. The Lunova Datum (M1-43-16) is the slim one, a 10.7 mm steel case around Mühle's version of the SW400-1, with up to 41 hours of power reserve, and it takes a 22 mm strap. The Lunova Tag/Datum, or Day/Date (M1-43-26), adds the weekday on Mühle's version of the SW220-1, also rated at up to 41 hours, and comes in titanium, which Mühle picks for its light weight and anti-allergic properties.

The Lunova Datum Chronograph (M1-43-06) is the thick one at 14.2 mm in steel. In its current form it runs on Mühle's MU 9413 automatic calibre, with a Mühle rotor, a Glashütte three-quarter plate and woodpecker neck regulation, up to 62 hours of power reserve and a 12-hour chronograph started from the pusher at 2 o'clock; it also shows the weekday. Every version has stop-seconds and a quick-set date, and the black dials carry applied indices with Super-LumiNova on the hour markers and hands.
