Two recently debuted blue-dialed watches, the Bell & Ross BR 05 GMT Sky Blue and the Oris Aquis Small Second Date 45.5mm, demonstrate how versatile —and attractive — the azure tint can be when perched on a wrist. And both debuts sport serious specs and can be worn anytime and in any workday or playtime environment.
Oris
If your typical day takes you in or near the water, the Oris Aquis Small Second Date 45.5mm ($2,900) is your best bet here given its much-greater-than-average 500-meter water resistance rating.
Oris notes that the watch’s water resistance rating is actually greater than the standard model within its Aquis dive series, which typically includes watches rated to 300 meters of water resistance.
The watch, with its ocean-inspired deep-blue dial, represents a new size the Oris Aquis time-and-date-only series. It retains all the dive-ready specifications you’d expect from Oris, including a small seconds indicator (at the 9 o’clock position) with a luminous hand, a screw-down crown with protection, a uni-directional rotating bezel with a ceramic insert, and either a metal bracelet or rubber strap equipped with the Oris-patented extendable security folding clasp.
Oris has launched an impressive selection of colorful watches in recent years, especially within its Big Crown series. Even the watchmaker’s ProPilot collection now includes hues unexpected within such a technical series.
The new Oris Aquis Small Second Date 45.5mm revels in its ocean-colored dial, bezel insert and rubber strap. (See below for detailed specifications).
Bell & Ross
Inspired by summer skies, Bell & Ross finishes its latest BR 05 GMT with a sky blue sun-ray pattern dial. Earlier BR 05 GMT models have only been available with a black dial or a white dial.
Framed by the Bell & Ross’s own circled-in-a-square case shape, the dial allows the wearer to determine time in a second time zone thanks to the blue-tinted GMT hand. With its easy-to-read large white arrow-shaped tip, the hand allows means wearer can quickly determine the hour in any of 24 timezones emblazoned along the graduated inner bezel. 
Bell & Ross enhances this flange with a sky blue and silver color treatment. The colors allow the wearer to further differentiate whether the second time zone hour is in the daytime (silver) or nighttime (blue). Bell & Ross coats the hands and the rhodium-plated baton-shaped indexes with a healthy amount of SuperLuminova.
Inside Bell & Ross fits its bedrock BR-CAL.325 movement, a Sellita-based automatic caliber. And, for all-weather wear, Bell & Ross supplies a screw-in crown to guarantee water resistance to 100 meters. (See below for detailed specifications.) 
Bell & Ross offers two types of attachment for the BR 05 GMT Sky Blue. The first is a stainless-steel bracelet and second is a blue rubber strap tinted to match the dial color.
