IWC Schaffhausen Aquatimer Chronograph Edition Boesch Ref. IW378204

Around 3,700 craft have been launched since 1920 by Boesch, the boatyard located on Lake Zurich. All made of wood. The reddish brown, highly polished mahogany is the mark of their exclusive craftsmanship. IWC presents a special edition of the Aquatimer Chronograph as a tribute to the iconic boat builders.

The watches from Schaffhausen share not only their high-quality craftsmanship with the exclusive motorboats from Kilchberg on Lake Zurich, but also an exclusive special position – they are built with passion. Similarly, IWC watches like the Aquatimer Chronograph, are also water sports enthusiasts through-and through.

The colour scheme of the special edition “Boesch” is obvious: mahogany. As such, it emulates the air exuded by the genuine article, the sleek motorboats, which are now being built by Boesch in its fourth generation. Their hulls and structural parts are made only from mahogany, the traditional boat building timber, with its unsurpassed properties.

The IWC Aquatimer Chronograph Edition Boesch (reference IW 378204) adopts this feature on its dial. And reddish brown is extremely becoming. Even on the back with a mahogany inlay and a stylized marine screw propeller. On the front side, too, a small discreet signature of the second-generation owner –Walter Boesch – points to the exclusivity of this limited edition.

This Aquatimer Chronograph is built as a diver’s watch with a pressure-resistance tested down to 12 bar. For diving it is equipped with the patented IWC system with a rotating inner bezel for measuring the dive time. This can be synchronized with the minute hand via the dual function crown at “4.00” – but only in the “safe”, anti-clockwise direction. The crown also serves as a button for resetting the chronograph, which can be started and stopped with the button at “2.00”.

The crown for setting the time or for activating the automatic movement is of the screw-in type. The stainless steel case with its dimensions of 44316 mm (diameter/height) has a convex sapphire glass that is antireflective on both sides and is supplied with a brown rubber strap to match the colour of the dial.
