Pierre DeRoche has added a GMT display and power reserve indicator to a 2017 limited edition of its TNT collection.
The watch houses a Dubois Dépraz automatic calibre in a 43mm case.
The usual skeletonised dials associated with the TNT has been replaced by a full dial that the company says makes it easier to read.
The watch has only one pusher because all the GMT operations are handled via the crown.
Two models are available, one with the titanium and steel case framing an anthracite black dial, the other with a black DLC-treated case and sand-toned dial and strap.
201 pieces are being made of each model.
