From designer to luxe, rich hues of blue reign supreme this season in watches. For color coordination to the nth degree, start with the gemstone: Blue sapphires or blue topaz pair well with color-coordinated alligator, lizard straps, python, or galuchat (stingray) exotic straps for alluring appeal. Another option: Highlight the deep-blue straps with white diamonds for a dazzling wintery look.

No matter what gemstone and strap style you choose, winter dressing has never looked so good as when highlighted with one of the blue beauties showing off the top brands’ signature settings and the highest-quality technological advances. Whether accented by a 12 o’clock diamond, a dial of 230 pavé diamonds, or even free-falling sapphires, we’ve chosen the four special watches in hues that will have you singing the blues.

De Grisogono’s bold Novantatre annual calendar watch ($306,800) is crafted in 18k white gold and meticulously set with 282 blue sapphires on the case weighing 25.60 carats. The dial is a pavé dream of 230 diamonds with day, date, and sub-seconds indication. This winter wonderland’s blue galuchat strap perfectly sets off the 95 sapphires.
