This 300 piece limited edition watch might look similar to the regular Mk2 Pro 600, but under the hood is Christopher Ward’s remarkable in-house SH21 movement, with its 120 hour (5-day) power reserve. On the outside there are a few visual clues which give it away as the ‘special one’: the most obvious is the face with its “5 day Chronometer” marking (the Chronometer part indicating its COSC certified accuracy). Less obvious is the date window being a little further over to the right than the regular 600. Finally it’s the case back, which is taller to make the room required to house the SH21’s rotor - not to mention the Chronometer Calibre SH21 wording as the final giveaway! I bought this watch in January of 2019, its a beautiful limited edition piece and is number 293 of the 300 pieces made, so very rare. I have never worn the watch and it comes with the original protective plastic coverings on the watch and strap along with watch documents, letter of purchase and COSC certificate and the rare limited edition booklet that has the certificate of authenticity. It will also be sold with the original box and outer box that it was delivered in. It's a superb example of the iconic trident which has become the signature watch of Christopher Ward. Please let me know if you have any questions, thanks for looking. Note: buyer will be responsible for shipping cost. Thank you
