\nFifty Fathoms Bathyscaphe Flyback Chronograph Ocean Commitment II
\nMAKE YOUR CASE
\nSome brands think highly of ceramic, and Blancpain is one of them. Previously championed by Rado and Chanel, ceramic cases have recently become all the rage, as it gives manufacturers far more control over things like colour and hardness. The new Blancpain Ocean Commitment II watch is no exception, with a case all in blue ceramic.\nSIZE MATTERS
\nThe case is chunky, to say the least. But its large dimensions (43mm and 15mm thick) are no doubt due to its ability to survive depths of 300-metres below the surface. The Chronograph Ocean Commitment II will also withstand drops and bangs on the surface, thanks once again to its hardy ceramic case.\nCASEY FLYBACK
\nThe original Bathyscape Flyback Chronograph movement was first introduced in 2014. The automatic calibre F385 runs at 5Hz (hi-beat 36,000bhp) with a 50-hour power reserve and 12-hour flyback chronograph. The sapphire glass case back gives the wearer ample view of the movement and its 18-karat gold rotor.\nOCEAN FRIENDLY
\nPrice for each of the 250-piece limited edition is around US$17,000, however for each piece sold a portion of that will go towards supporting scientific expeditions as part of Blancpain's Ocean Commitment project.

\nTHE SKY'S THE LIMIT
\nIt doesn't take much to understand the concept behind Jacob&Co's latest high-mechanical wonder. However, "After the first version, we wanted to connect the watch with the stars," says Luca Soprana, the specialist behind this creation. As such, the extremely complicated timepiece features a time display and a tourbillon, as well as representations of both the Earth and the moon (which rotate on spokes around a central axis). All of this is visible beneath a large sapphire dome. The new Astronomia also incorporates a sidereal-time display, with real-time tracking of both the stars and zodiac calendar. A star chart lies beneath the inverted dome over the movement and indicates which heavenly bodies are above the manufacture's Geneva latitude. The dome rotates imperceptibly – about one degree per day to account for the orbit of the Earth around the sun (which is every 23 hours, 56 minutes and 4.1 seconds). To account for that time discrepancy, Soprana had to create a special planetary gear to render the 4-minute speed reduction.

Longines Heritage Military
\nBased on a watch Longines produced back in 1918 (and currently part of its museum collection) the new Longines Heritage Military certainly looks the part – with clean lines that ape the original. A welcome upgrade to the old-school dial is the Super-LumiNova, and it's powered by an automatic movement.

Jaquet Droz Petite Heure Minute Thousand Year Lights
\nWith remarkable detail and colour intensity, the dial of Jaquet Droz's latest women's watch seems to leap across the room. The secret to its attraction lies beneath the black lacquer dial and subtle recesses – created by intaglio engraving – that hold translucent-coloured paint and floral design.
