Stepping into a swanky suite at The Ritz-Carlton Kuala Lumpur, our eyes immediately darted to the large box in the middle of the room. We knew we were there to see a watch, but what exactly were we about to be shown? The large, rectangular box was covered in smooth black leather; luxurious and promising.

Once the latch was undone, we came face to face with a single IWC Portugieser Constant-Force Tourbillon resting snugly on an automatic winder housed in the box. As its name suggests, the machine works to wind the watch placed upon it so the time remains as accurate as possible. Several comments on what a great gift the winder would make later, we redirected our attention to the main agenda — the highly customisable IWC Portugieser Constant-Force Tourbillon.

A variation of the timepiece pairing a blue dial with a platinum case.

Let’s start with the basics. The case is 46mm wide and comes in red gold or platinum. As for the dial, choose from four classic colours — ardoise, black, silver or blue — whether by pairing with the same colours of straps or otherwise. The straps are made by Santoni and colour choices include Santoni alligator black, dark brown or blue while the stitching colour is either red gold or platinum for the outer side and orange on the inside.

This beaut variation comprises an ardoise dial, red gold case and brown alligator straps by Santoni. Choices, choices.

Moving on to the dial, a double moon phase feature shows the state of the moon in both the northern and southern hemispheres. Powered by the IWC-manufactured calibre 94800, the watch has a power reserve of 96 hours. At the heart of it all, the constant-force tourbillon is set to a frequency of 2.5 Hz so the system is able to wind the balance spring every second.
