Summary of Contents for Christopher Ward C900

  • Page 2 Johannes’s dream of allowing the owner of such a complicated movement to see and understand how the movement really works. The C900 is the realisation of that dream and is a perfect example of how, through innovative design as well as fair and honest pricing, Christopher Ward is determined to make fine watchmaking accessible to as many people as possible.
  • Page 3 Story by Simon de Burton Nothing unites young and old so effectively as a shared passion. For some it is sport, for others it might be music, art, classic cars, travel or history. But the common denominator which enabled 28-year-old Johannes Jahnke and 87-year-old Jean Fillon to form an almost instant bond is their mutual fascination for horology - or, more specifically, for solving the problems it so often produces.
  • Page 4 Since 2008, however, Jahnke has worked with a small, high-end firm in the watchmaking town of Biel, which devises, develops and produces watch mechanisms for a few select watch brands – one of which is Christopher Ward. Here, Jahnke is allowed to work without constraints and allowed to realise, or attempt to realise, his wildest watch-making dreams.
  • Page 6 Unitas movement. More than six months later, this has come to fruition in the form of Christopher Ward’s most sophisticated and complex watch to date, the C900 SP – a beautifully understated, classic-looking chronograph powered by its own, exclusive, monopusher movement.
  • Page 7 The result was an extensively reworked movement with a new main plate, bridges, winding mechanism, centre and second wheels. A swan neck adjustment system was added and a clean, uncluttered dial designed at the Christopher Ward studio that allows for the inclusion of a continuous seconds sub-dial and a 30-minute totaliser. Inverting the watch, however, reveals the beauty of the new movement in all its glory.
  • Page 8 C900 will always be a very special watch for me. The C900 SP ‘owner’s club’ will not, however, be a crowded one. Due to the complexity of its movement, just 250 examples of the C900 SP, in this form, will be available worldwide.
  • Page 9 In 2008 Johannes, eager to produce watches that were not merely the preserve of monied collectors, was asked to join Jörg Bader, Christopher Ward’s Swiss partner. The partnership with Christopher Ward that produced the exciting Single Pusher Chronograph suits Johannes particularly well as the relationship allows him to bring luxury watches within the reach of more people.
  • Page 11 The following pages are designed to give you a unique insight into how the JJ02 Calibre complication inside your C900 really works. Drawn from Johannes Jahnke’s original CAD drawings, a little time studying them will not only give you a thorough understanding of how your watch works but also take you inside the mind of a master watchmaker.

  • Page 13 the 3 cycleS of the SinGle PuSher moVement 1. Starting the chronograph After pressing the Pusher (Fig 2) which sits inside the Crown, the Column Wheel pusher pushes the Column Wheel one cog forward. The Column Wheel has 18 teeth and turns 20 degrees per step. The Column Wheel Jumper locks the Column Wheel into the new position (Fig 3).
  • Page 14 When the Column Wheel turns, the Break Lever releases the Centre Wheel (Fig 4). (Fig.4)
  • Page 15 The Reset Lever now releases the Heart of the Centre Wheel and Minute Counter Wheel (Fig 5). (Fig.5)
  • Page 16 The Clutch falls into the space between the Columns so that the Intermediate Wheel, which turns continuously with the Second Wheel, is connected to the Centre Wheel (Fig 6). The Centre Wheel now turns in the same direction as the Second Wheel. (Fig.6)
  • Page 17 The Sliding Gear Lever falls between the Columns and the Minute Counter Intermediate Wheel moves to the centre and engages the Minute Counter (Fig 7). (Fig.7)
  • Page 18 The Finger-Piece, which is fixed to the Centre Wheel, pushes, after 60 seconds, one tooth of the Minute Counter Intermediate Wheel. The Minute Counter Wheel turns one step forward when the Minute Counter Intermediate Wheel Jumper rests between the next two teeth (Figs 8 & 9). This procedure repeats for as long as the chronograph is working.
  • Page 19 2. Stopping the chronograph When you press the Pusher for a second time the chronograph stops (Fig 10). (Fig.10)
  • Page 20 The Column Wheel turns one tooth forward, the Brake Lever falls into a space between the Columns and holds the Centre Wheel in position (Fig 11). The Clutch separates the Intermediate and Centre Wheels (Fig 12). (Fig.11 (Fig.12)
  • Page 21 The Sliding Gear Lever moves out of the centre and separates the Minute Counter Wheel (Fig 13). (Fig.13)
  • Page 22 3. Re-setting the chronograph Pressing the pusher for a third time moves all the pieces of the chronograph back into the start position (Fig 14). (Fig.14)
  • Page 23 The Column Wheel again turns another single tooth forward. The Brake Lever releases the Centre Wheel (Fig 15). The Reset Lever falls into space between the Columns and pushes the chronograph wheels back to the start position by turning the Hearts through pressure (Fig 16). (Fig.15) (Fig.16)
