The new Blue Sensation watch is constructed around a hand-wound mechanical caliber, which utilizes as its base a Patek Philippe split-seconds chronograph movement.
It was developed by the house in 1889 and delivered to Tiffany in 1890. Completely disassembled for more than 20 times, the mechanism underwent afterwards a considerable technical evolution.
The base plate of the movement is hand-skeletonized, guilloched and treated with blue platinum. The caliber also incorporates a changed in shape three-quarter plate. Just as well skeletonized by hand and quilloched, it is coated with rhodium and rose gold.
Every single bridge was skeletonized to change the shape, quilloched and treated with rhodium. The hand-engraved cock is coated with rhodium and rose gold. The caliber also boasts flame blued steel screws.
Embellished with 26 jewels, the movement operates at a frequency of 18,000 vibrations per hour and offers a power reserve of about 30 hours.
The mechanism in question serves to animate an array of useful functions. They can be read off on a hand-skeletonized sterling silver dial, featuring a rare Breguet frosted finish. The face of the new Grieb & Benzinger watch demonstrates the blue platinum-coated base plate and overlapping displays, performed in the brand’s signature style.
The dial indicates hours, minutes and seconds as well as sweep chronograph minutes. Taking care of them are steel blued hands. They are joined by a rose gold-plated split-seconds hand. Equipped with Roman numerals, the counter at 3 o’clock is in charge of hours. The subsidiary seconds are ticking away in a counter at 9 o’clock. The upper part of the display exposes the company’s logo.
As it was mentioned above, the new Blue Sensation watch is available with a solid platinum case, which measures 49 mm in diameter. It is endowed with a crown and a pusher, manufactured from the same material and embellished with guilloche motif on their top. The front part of the case is protected by an anti-reflective domed sapphire crystal. The sapphire glass is also used for the screw-in case-back.
The new Grieb & Benzinger watch is coupled with a blue alligator leather strap, finalized by a platinum buckle. With its weight equal to 165 grams, this model happens to be the heaviest platinum timepiece in the world.
