Mühle-Glashütte M 29 Classic watches

The Mühle Glashütte M 29 Classic is a steel automatic watch from the Glashütte maker that dates its precise timekeeping to 1869. It appeared in 2013, and its design looks back to the Model 29 indicator gauge, from the time when Robert Mühle made precision measuring instruments for Glashütte's watch industry. The polished 42 mm case comes from the 29er Big, a watch built for use on the water.

The gauge shows in the dial. Narrow hands like those on workshop gauges sweep a wide dial left open by a thin bezel, with simple black numerals and red indices. The case is 42.4 mm across and 11.3 mm thick, vertically brushed, with a brushed bezel top and polished bezel edges, a polished screw-down crown and crown protectors. It has a sapphire crystal with anti-reflective coating and 100 m of water resistance.

Inside is a Sellita SW200-1 automatic, not an in-house movement, which Mühle reworks with its woodpecker-neck regulation, a signed rotor and its own finishing.

Each version comes on a steel bracelet (references ending MB) or a leather strap (LB). The standard M 29 Classic (M1-25-53 black, M1-25-57 cream) has a centre seconds hand. The Kleine Sekunde (M1-25-63 black, M1-25-67 cream), added in 2014, moves the seconds to a subdial and uses a Sellita SW290, built on the SW200, again with Mühle's regulation and its own rotor; its case is a fraction thinner at 11.2 mm. The Einzeiger (M1-25-59) has a cream dial.
