This year, the watch brand Mühle-Glashütte celebrates 145 years since the company was founded by Robert Mühle, but also the 20th anniversary of the re-establishment of the family business by Hans-Jürgen Mühle. To mark this double anniversary, the German watchmaker presented three special edition models powered by two manufacture calibres.
The first and more precious model is the Robert Mühle Auf/Ab Gold, a limited edition of 20 pieces in red gold. The polished and satin-brushed 44 mm case, with its finely notched bezel, is reminiscent of the marine chronometers that have been produced by Mühle-Glashütte since 1994.
The hand-wound calibre RMK 01, visible through the transparent case back, is the first Muhle-Glashutte movement fully developed in house and featuring an engraved balance cock with woodpecker neck fine regulation. Beating at 21,600 vph, if offers a 56-hour power reserve.
The steel version of the Robert Mühle Auf/Ab, a limited edition of 145 units, differs from the red gold version for the silver dial with blued hands.
The third model, the Robert Mühle Kleine Sekunde, is characterised by the silver dial with Arabic numerals, blued hands and small seconds at 6 o'clock.
The steel case maintains the diameter of 44 mm but it is slightly thinner than the Auf/Ab models (11.8 mm instead of 13 mm) because the hand-wound movement RMK 02 does not feature the power reserve module mounted on the RMK1.
145 pieces of the Robert Mühle Kleine Sekunde will be produced.
