Case material: Steel; Charge: Manual; Conditions: New Presentation condition : With dealer guarantee ; Model: Easy Diver Price on request Gmtbroker Reference: SE4802/9/0 The Roger Dubuis Just For Friends watch is a very symbolic timepiece because it was created specially by the former CEO of Roger Dubuis Mr. Carlos Diaz with his friends in mind. One of his friends commented that it is sad that all diving watches had a solid case back that hid the movement. Diaz then decided to launch a dive watch collection with a transparent case back capable of reaching nearly 1000ft. Hence, a watch "just for friends" was born. This particular model is made of Stainless Steel with a 18kt White Gold Bezel and boasts a textured Champagne Dial. The dial boasts luminescent index hour markers which indicate the standard hours and minutes. The dial also features a flying tourbillon at the 7 o'clock position. The case back is transparent to further show off the watch's unique mechanics and the strap is made of sturdy black rubber with a deployment clasp. Water resistant to 300 meters/985 feet.
