About this watch

The Oris Big Crown Small Seconds Date Swiss Hunter Team is a remarkable timepiece that embodies the perfect blend of functionality and artistry. This stunning watch reflects a rich heritage in Swiss watchmaking, with a storied history rooted in aviation and a commitment to traditional craftsmanship.

With a frequency of 28,800 vibrations per hour and a 38-hour power reserve, this movement powers the hour and minute hands as well as a subsidiary second hand at the 9 o'clock mark. The watch's rugged elegance is characterized by its matte black finish, mixed indexes, and round case measuring 46mm in diameter. The dial is designed with clarity in mind, featuring sword-shaped hands for easy readability and a date display cleverly incorporated into the design. The watch's durability is ensured by its stainless steel construction and PVD coating, paired with scratch-resistant sapphire crystal and a water resistance of up to 100 meters. As part of a limited edition of just 1958 units, this watch offers exclusivity and a unique charm that sets it apart from other timepieces.
