The BCHH Sovereign

 

The Sovereign is the supreme expression of the luxury sports watch - of impeccable construction and craftsmanship, encased in a sleek futuristic case of solid platinum, with a magnificent ultra-thin microrotor movement finished to the highest standards of classical haute horlogerie. Available with a choice of aventurine, white jade, green jade or solid platinum dials.  

Do note that the engine-turned guilloché pattern of the dial may be completely customised to your choice. The pattern depicted in the images here is the "Ecaille de Poisson", which we believe particularly exemplifies the harmony of the Sovereign. The subsidiary seconds dial is encircled with concentric guilloché circles. Our guillochage is done the traditional way by a skilled artisan engine-turning the pattern by hand using centuries-old antique machinery, at dial atelier Comblémine.
