Along with the small seconds shared with Calibre 401, the 403 includes a pointer date, ubiquitous with the other Big Crown pilot watches. This is a very clean look that sets it apart from their standard Divers Sixty-Five, along with other more subtle differences throughout, now with small text circling the sub-dial proudly lauding the properties of the 401, shared across the family of calibers.Ĭalibre 403 has manifest in this year’s iteration of Oris’s Holstein Limited Edition, modeled after the Big Crown line. The 401 makes it’s debut in the latest iteration of Oris’ Carl Brashear Limited Edition, still in bronze and blue, now with a small seconds dial between center and 6’clock.

For more of a dive into 10-year service intervals, check out when I really dove into it here, but rest assured I’ve done my homework, and Oris’s Calibre 400 and how the brand is standing behind it is pushing the industry into new territory.Īfter a very short period of time, relatively speaking, we now have two other movements: Calibre 401 and Calibre 403.

No other company is doing that, not to that extreme. I cannot impart to the reader how significant that last bit is. More expensive than the brand’s base model Aquis by about $1,300 (but still well under $5,000), what that premium gets you is a movement that is antimagnetic, a 5-day power reserve, and a 10-year warranty (and suggested service interval). But for those of you that are familiar or can’t be bothered, let me refresh you: the Calibre 400 was first introduced in the new Aquis Date Calibre 400 (and has only been extended to another diver, the Aquispro Date Calibre 400). To those of you not familiar with the Calibre 400, I highly recommend you read this introduction. But with movements numbering “400”, “401”, and “403”, one has to ask: Where (and what) is “Calibre 402”? I have a hunch… All of these are built off the base architecture of the Calibre 400, a revolution in watch engineering, longevity, and economics. On June 1, the newest Oris Holstein Limited Edition was released using the never-before-seen Calibre 403 with pointer-date and small seconds to the tune of a scarce 250 available pieces. Starting with the inaugural “Calibre 400”, name of both movement and watch, a time/date Aquis, we were then quickly given the newest iteration of the Carl Brashear diver in bronze with “Calibre 401”, a small seconds variant of the base 400.

Over the past months, Oris has released a handful of novel and formidable in-house calibers.
