When Oris introduced the Calibre 110 in 2014, it marked a milestone in the brand’s more than 120-year history. Entirely developed and manufactured in Hölstein, the hand-wound calibre offered an impressive ten-day power reserve from a single barrel and featured a patented non-linear power-reserve indicator. The Calibres 111 through 115 expanded on this platform with additional complications, each underscoring Oris’s renewed commitment to traditional watchmaking. With the debut of the Calibre 113, Oris continues this trajectory. The movement combines the long power reserve and patented display with a so-called “business calendar.” In addition to day, date, and month, it provides the rarely seen indication of the calendar weeks. All functions can be adjusted via correctors and a fine-adjustment device, while a stop-seconds mechanism allows precise time setting. The regressive power-reserve display, positioned at 3 o’clock, slows its progression as the mainspring nears depletion, ensuring a more intuitive reading of the remaining energy.

The watch housing this sophisticated calibre remains true to the Big Crown design first introduced in 1938, with a round case, oversized crown, and ergonomic proportions. For this edition, Oris complements these hallmarks with a bold aesthetic: a mint-green dial accented by pink subdials and contrasting details in gold and white. Super-LumiNova coating enhances legibility in low light. The stainless-steel case measures 43mm in diameter and 13.5mm in height, is water-resistant to 50 meters, and features a domed, antireflective sapphire crystal. A sapphire caseback offers a view of the movement and its impressive mainspring barrel.

The Big Crown Calibre 113 is paired with a multi-link stainless-steel bracelet with folding clasp. It will be available in September 2025, priced at $8,100.

Oris has long been celebrated for its independent spirit and technical ingenuity. In 2014, the company made headlines with the  ProPilot Altimeter, the first watch to combine an automatic mechanical movement with a mechanical altimeter. Two years later, a carbon-fiber-cased version expanded the measuring range and introduced a 56-hour power reserve. This year, the ProPilot Altimeter embarks on a new mission in collaboration with George Bamford and his London-based Bamford Watch Department. Launched at the Geneva Watch Days 2025, the Oris x Bamford ProPilot Altimeter “Mission Control” is a limited edition of 250 pieces.

The watch features a 47-mm case made of carbon-fiber composite, complemented by a knurled bezel and a gray PVD-coated titanium caseback. The latter is engraved with a conversion table from feet to meters. Despite its technical complexity, the case remains water-resistant to 100 meters. At its heart ticks the automatic Calibre Oris 793, based on the Sellita SW300, offering hours, minutes, central seconds, a date at 3 o’clock, and a 56-hour power reserve. A patented crown system at 2 and 4 o’clock controls the dual timekeeping and altimeter functions. The mechanical altimeter measures up to 19,700 feet (approximately 6,000 meters).

The black dial is enlivened by high-contrast accents in yellow, lime, and red. Beyond evoking a touch of 1980s sneaker culture, these flashes of color significantly improve legibility. As with the Big Crown 113, the hands and markers are treated with Superluminova. A black textile strap with color-coordinated leather lining and a titanium folding clasp with fine adjustment completes the watch.

The Oris x Bamford ProPilot Altimeter “Mission Control” is priced at 6,700 Swiss francs (approximately $8,370).
