Elevate your horological rotation with this commanding Oris Classic XXL Worldtimer 7513. Introduced during the early 2000s, Reference 7513 represents the modern evolution of Oris’s iconic travel complications. By expanding the case architecture to an imposing 40mm “XXL” profile while retaining the manufacture’s most celebrated multi-time-zone movement, this reference perfectly balances robust contemporary wrist presence with high-level Swiss mechanical ingenuity.

Patented Push-Button Oris Calibre 690 Movement

At the core of this timepiece is the legendary Oris Calibre 690 dual time watch movement. Developed in-house by Oris engineers, this patented 30-jewel automatic caliber transformed travel timepieces by introducing effortless push-button adjustment. Rather than unscrewing crowns or turning internal bezels, two ergonomic pushers integrated along the case flank allow you to instantly jump the central local hour hand forward (at 4 o’clock) or backward (at 8 o’clock) in 1-hour intervals. Most impressively, the date complication at 6 o’clock is synchronized directly with the local hour hand—meaning if you cross the international date line at midnight in either direction, the date automatically advances or reverses accordingly.

Aviation-Inspired High-Legibility Dial

The matte black dial is engineered for rapid visual orientation in any setting. Bold, luminous Arabic numerals pair with an outer 5-minute track, offering sharp contrast and immediate legibility. At 3 o’clock, a dedicated 12-hour subdial tracks your home time (T2), complete with a clever miniature day/night aperture to track whether it is daylight or evening back home at a single glance. A continuous subsidiary running seconds subdial at 9 o’clock balances the dial face symmetrically, while broad luminous sword hands deliver excellent nighttime visibility.

Contemporary 40mm Classic XXL Case & Steel Bracelet

Engineered in solid stainless steel, Reference 7513 upgrades traditional vintage dimensions to a modern 40mm diameter. The case features sculpted, downturned lugs, a stepped bezel, and a flat scratch-resistant sapphire crystal designed for daily resilience. The reverse features an exhibition caseback showcasing the finely decorated movement and high-grade winding rotor. Fitted to its original, supple multi-link stainless steel bracelet with a secure deployment clasp, this Oris Worldtimer 40mm black dial drapes comfortably on the wrist, transitioning effortlessly from business tailoring to casual weekend attire.

An Iconic Mechanical Traveler’s Instrument

For collectors and frequent travelers who demand genuine mechanical substance without the fragility of conventional modular GMTs, this vintage Oris travel watch stands in a league of its own. Combining independent Swiss watchmaking heritage, everyday utility, and modern proportions, this pre owned Oris stainless steel bracelet watch is a versatile addition to any curated timepiece portfolio.
