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 using a Bluetooth Interface with any smartphone or tablet. The Troja 16 M is equipped with the extraordinary movement from the Classica Secunda 1995, 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.
