Erwin Sattler’s Troja M II Turns the Longcase Clock Into a Collector’s Cabinet

Erwin Sattler has built its reputation on the kind of horology that lives well beyond the wrist.

For 2026, the German maker is leaning into that idea with the Troja M II, a new longcase clock series designed not only to keep time, but to anchor a serious watch collection at home.

The collection comprises three models, the Troja 16 M II, Troja Lunaris M II and Troja Sonata M II, each combining a mechanical longcase clock with 16 integrated watch winders.

A longcase clock built around a watch collection

The Troja M II is best understood as furniture, horology and storage architecture in one object.

Erwin Sattler produces its clocks, nautical instruments, table clocks and wristwatches in Gräfelfing near Munich, and the Troja M II sits at the more monumental end of that world.

The Troja 16 M II measures 219.5cm tall, 45.5cm wide and 50cm deep, with a black varnished walnut case and metal inlay.

Its most theatrical feature is built into the sides of the case, where eight programmable watch winders on each side can extend remotely.

Fully extended, the clock reaches 70cm across, giving the piece a mechanical presence that goes well beyond a conventional longcase clock.

The base also functions as a safe for additional valuables such as watches or jewellery, and integration with home security systems is available on request.

The Troja 16 M II keeps the regulator spirit visible

The Troja 16 M II is powered by the Sattler calibre 1965, based on the Classica Secunda 1995 M.

Its partially openworked dial reveals the mechanism, while a one-metre pendulum beats once per second.

The movement has a 30-day power reserve, so the clock only needs winding once a month.

The display follows a regulator layout, with hours, minutes and seconds indicated on separate scales.

Dial and case interior finishes include a light silver-white option and a full black edition, giving the same architecture two very different moods.

Lunaris and Sonata add calendar and sound

The Troja Lunaris M II takes the series in a calendar-led direction.

Powered by the calibre 1915, it adds day of the week, date and moonphase indications to the hours, minutes and seconds.

The dial language blends classical and contemporary cues, with vertical brushing, a railway minute track, Roman numerals, visible screws and an open-heart aperture at 12 o’clock.

The Troja Sonata M II is the acoustic expression of the collection.

It uses the Sattler calibre 2015 and features a chiming complication that sounds the time every half hour.

Its display includes hours, minutes, seconds and moonphase, making it less calendar-driven than the Lunaris but more ceremonial in daily use.

Across the three models, the appeal lies in the mix of traditional hand craft and modern domestic utility.

Details & Specifications

The Troja M II is not aimed at someone looking for discreet storage or a simple way to keep automatic watches wound.

It’s for the collector who wants the mechanics of timekeeping to occupy a room, with the wristwatch collection quite literally built into the clock that governs it.
