The base of the clock houses a safe which provides space for all kinds of treasures. To make full use of the depth that is gained here, 16 remote-controlled watch winders are also housed in the rear section of the case. Along with their technology partner, Beluwo®, the Erwin Sattler manufacture has developed new, large wristwatch-holders which provide enough space for larger timepieces. Each unit is equipped with its own precision motor and can be individually programmed via Bluetooth, any smartphone or tablet. The Troja Lunaris M is equipped with the extraordinary movement from the Classica Secunda 1915, whose silver-plated dial emphasises the value of the lovingly handcrafted, domed hands. The pendulum, at a stately length of approximately one metre, swings once every second in an elegant and calming cadence.
The Troja is available with four different movements: Troja 16 M with the movement from the Classica Secunda 1995, Troja Lunaris M with the movement from the Secunda Lunaris, Troja Sonata M with the movement from the Secunda Sonata, Troja Opus Temporis with the movement from the Opus Temporis.
