The Reason
A visually interesting cam driven calendar mechanism built onto the brands manufactured own calibre.
The Roswell 08 is part of the Schwarz Etienne Roswell collection. Influenced in design by the Roswell flying saucer incident of 1947. The automatic calibre with date at 9 o’clock, small seconds animation at 11 o’clock has a power reserve of 86 hours.
The total thickness of the case 12.24mm, diameter 45mm. Made from stainless steel. Water resistant to 50 meters. Calibre ISE 100.11 Thickness: 6.30mm and diameter 30.40mm. Power Reserve 86 hours. Automatic winding.
Please move the cursor across the image below, (or by finger on a smart phone), to rotate the watch.
The case back is held by 6 screws (removed below). Hidden by the case back when it is in place are an additional 8 screws, 4 which hold the bezel and 4 which secure the shoulders into the case centre.
On the inside of the case back, and sitting on the rear of the movement is a disc with ‘Lenticular printing’ with a “Matrix” image in the back ground. The brands name in the foreground which disapears depending on the angle the case back is viewed.
The disc removed from the rear of the watch showing the back of the movement.
The dial fixed to the inside of the bezel.
The bezel and dial completely removed showing the full date ring and calendar mechanism.
The movement removed from the case.
The hands removed from the watch.
Brass with rhodium treatment and Super-LumiNova®
The calendar ring and its holding bridges removed.
Close up of the calendar mechanism with the dial, hands and date disc removed.
The calendar module removed (recto-verso) with the principle levers still in place.
The large operating lever and indexing pawl held on wide diameter columns for stability.
The manual date changing lever viewed from under the module.
Recto-verso of the movement with the case back plate and calendar module removed.
The green bombé disc that turns once a minute fixed to the extended pivot of the forth wheel.
The automatic oscillating rotor removed.
The rotor is covered with an engraved circular brown disc which can be see on the dial side of the assembled watch.
Underneath the black disc is the tungsten carbide weight.
The balance wheel and cock removed.
The Swiss lever and escape wheel bridge removed.
Each movement has a unique serial number engraved on the side of the main-plate
The escapement, rotor weight and barrel ratchet wheel removed.
The upper bridge holds in place the rotor weight and the automatic train, here removed.
The design of the Schwarz Etienne movements are modular, allowing the choice of double barrels with large torque, or less torque with an automatic.
The entire rotor mechanism can in essence be exchanged for a second barrel when the design process is being decided.
The automatic assembly removed.
The 3/4 barrel bridge removed showing the full train.
The main-plate dismantled
The small silver coloured central bridge below reverses the drive of the hands through the movement.
The rear of the calibre dismantled with the exception of the setting mechanism and part of the motion work.

Summary
The Roswell models are based on a circular cased timepiece given a modern twist to associate with the Roswell concept. The case, on close examination is inventively designed with the internal angular sides on the shoulders that integrate with the profile of the case center. The visible calendar mechanism makes for an alternative form of animation.
