Double Balancier Convex by Greubel Forsey
The Swiss Haute Horlogerie studio patented the dual balance wheel concept in 2007, the idea that averaging timekeeping with two different balance wheels set on different planes is more accurate than a single balance wheel.cheap replica watches
Since then, Greubel Forsey has implemented the concept in several different iterations, experimenting with different mounting angles before reaching this configuration, which sees the dual balance wheels set at opposite 30-degree angles , and is served by a constant spherical differential.
The component takes up half the dial space inside its curved, wrist-hugging 43.5mm titanium case. The hour and minute hands are in the center, the small seconds are at four o'clock, and the hands on the spherical differential show its four-minute rotation. Skeleton hands are located near three o'clock and indicate the remaining length of the 72-hour power reserve of the hand-wound movement.
The Double Balancier Convex is also water-resistant to 100m in light of the brand's new strategy to create more sporty, functional cheap watches for sale.
Jacob & Co. Introduces Exclusive Astronomia Solar Zodiac Tourbillon Black Titanium
Jacobs & Co.'s approach to creating luxury handcrafted timepieces is to think outside the box, which will continue to connect the watch industry to the rest of the world. Jacob & Co. came up with the world and released the new Astronomia Solar Zodiac. The rounded matte finish of the case is derived from the DLC's treatment of the 44mm titanium case, completely changing the look of the traditional Astronomia. Using the in-house hand-wound JCAM19 movement, this piece revolves around the Milky Way painted dial, unifying the entire solar system. Seven planets are represented by semi-precious hemispheres: Mercury's white granite, Venus' ruby, Mars' red jasper, Jupiter's Peterstone, Saturn's tiger's eye, Saturn's blue calcite, and Neptune's lapis lazuli. The time display displayed through the Zodiac Symbolic Platform is driven using an infinitesimal differential system to keep time in a very clear way. The large blue alligator strap and black PVD titanium clasp contrast the Astronomia's dark exterior. Jacob & Co. pushes the limits of watchmaking again with the Astronomia Solar Zodiac Black.Jacob & Co. Astronomia Solar Jewellery
