H. Moser & Cie. release bold and beautiful $40,000 perpetual calendar

H. Moser & Cie., a watch brand beloved by die hard horological nuts, has just unveiled its latest collection of perpetual calendars.

The watch world has a few complications that are far harder to make then the rest. Tourbillons, minute repeaters and perpetual calendars are some of the most, if not the three most difficult things to put into a wrist watch.

Perpetual calendars are crazy little things that can keep track of the date perfectly without you having to adjust for months that don’t have 31 days.

They are capable of calculating the different number of days in each month, and can even calculate leap years. All of this is done without batteries or electronics, just cogs and gears.

The Pioneer Perpetual Calendar MD is the brand’s latest entry into the world of perpetuals and it’s a stylish one. The watches use two large date windows to display the date and month, as well as a leap year cycle indicator on the reverse of the watch. It also displays the hours, minutes and small seconds, as well as a power reserve indicator.

Previous perpetuals from the brand have shied away from this bold double window display, the Endeavour perpetual instead opts for a small fourth hand on the dial to display the month. This new line is the first time the brand have gone for the striking double window display.

The dials are highly legible and modestly have hour markers around the dial in the form of little Superluminova dots.

Housed in a 42.8mm steel casing, the in-house movement, which can be admired via the sapphire back, has a power reserve of up to a week. Excluding the sapphire crystal components, the watch is a mere 11.3 mm thick.

Limited to 50 models each, the Pioneer Perpetual Calendar MD comes in a burgundy sunburst dial variant or a ‘Funky Blue’ variant. The blue version uses wedge hour indicators as well as dots. The dials use a fumé method, meaning the intensity of the colour radiates out the centre of the dial. Smoke-applied dials have heat applied to them and that heat gradually lowers away from the centre, giving the colour change.

Presented on a leather strap, the watches clock in at a hefty US $39,900 each.
