The intense colour of the turquoise at the centre of the dial and at the back of the tourbillon cage immediately draws the eye. Around it is a guilloché pattern, an undulating motif that recalls the rippling waters of the famous strait. The waves of this mechanical decoration seem to shuttle from one index to the next, as if carried by the rhythm of the hours. The inspiration for the markers comes from the Ottoman numerals on the clock of the Tophane-i Amire Sanjak Tower, an emblematic building that is an integral part of Istanbul's cultural heritage.

Guilloché is an equally precious heritage. This craft consists of engraving fine lines on the metal with extreme precision, to form a wave pattern that is complex and lively. For the grade-5 titanium edition, this decoration is coated with grey Neoralith. A translucent burgundy varnish is applied for the 18-carat red gold edition. In both versions, the material captures the light and reveals the full depth of the guilloché.

The turquoise radiates a unique colour, somewhere between sky and sea. For millennia, it has been used as a symbol of protection and is associated with wisdom, clarity of mind, and harmony with the elements. In the GALATA BLUE, it evokes the beauty of the Bosphorus and embodies the spirit of the place. Its presence, rare in watchmaking, gives the watch a strong aesthetic and symbolic visual presence.
