Introduction

The Oris ProPilot X Kermit (ref. 01 400 7778 7157-Set) is a watch that refuses to take itself too seriously—yet delivers serious horological credentials. Named after the iconic Muppet, its vibrant green dial and titanium construction make it a standout in the crowded field of everyday sports watches. But beyond the playful color, this is a tool watch built for real-world wear, with a five-day power reserve, COSC certification, and a case that disappears on the wrist.

For the young collector who values both personality and performance, the ProPilot X Kermit offers a rare blend of whimsy and engineering. It’s not a limited edition in the traditional sense—Oris produced it as a regular production model—but its unique dial color and the brand’s growing reputation for in-house movements make it a compelling choice. This review focuses on how it actually wears: lug-to-lug comfort, legibility, and what survives a week on the wrist.

I spent two weeks with the Kermit, wearing it through office days, weekend hikes, and casual dinners. Here’s the full breakdown.

Manufacture History

Oris was founded in 1904 in Hölstein, Switzerland, and has long been known for producing robust, accessible mechanical watches. The brand’s focus on in-house movements, particularly the Caliber 400 series, marks a significant step toward independence and technical credibility. The ProPilot X family, launched in 2021, represents Oris’s modern take on the pilot watch, blending aviation heritage with contemporary materials.

Movement

At the heart of the Kermit beats the Oris Caliber 400, an automatic movement entirely developed and manufactured in-house. It offers a 120-hour power reserve (five days), beats at 28,800 vph, and is COSC-certified for chronometer-level accuracy. The movement features 21 jewels, a bi-directional winding rotor, and anti-magnetic properties thanks to a silicon escape wheel and anchor. Finishing is industrial but attractive: perlage on the mainplate, circular graining on the rotor, and blued screws. The date is displayed at 6 o’clock and is set via the crown (no quick-set, but the long power reserve means you rarely need to adjust it).

Specifications

  • Case diameter: 39mm
  • Case thickness: 12.5mm
  • Lug-to-lug: 46mm
  • Case material: Titanium
  • Crystal: Sapphire with anti-reflective coating
  • Water resistance: 100m
  • Lume: Super-LumiNova on hands and indices
  • Bracelet/Strap: Titanium bracelet with folding clasp, plus additional green rubber strap

Wrist Feel

The first thing you notice is the weight—or lack thereof. At just 39mm in diameter and 46mm lug-to-lug, the titanium case sits like a feather on the wrist. The integrated bracelet tapers elegantly from 20mm to 16mm at the clasp, and the links are slim enough to conform to any wrist shape. The green rubber strap (included in the set) is even more comfortable, with a soft texture that never sticks or chafes.

Balance is excellent: the watch never feels top-heavy, and the low-profile crown (signed with the Oris logo) doesn’t dig into the hand. The clasp, while lacking a micro-adjust mechanism, has three adjustment holes and a diver’s extension—enough to get a perfect fit. Over a week of daily wear, I forgot I was wearing it. That’s the highest compliment for a tool watch.

Accuracy

The Caliber 400 is COSC-certified, and my sample ran consistently at +2 seconds per day over a week of mixed wear. The 120-hour power reserve means you can take it off Friday evening and pick it up Monday morning still running. No winding, no resetting—just pure convenience. Day-to-day, expect chronometer-level precision with minimal deviation.

Occasions

The Kermit is versatile enough for sport, daily wear, and travel. Its 100m water resistance and screw-down crown make it pool-safe, while the green dial adds a pop of color to casual outfits. It’s not a dress watch, but it can easily accompany you from a business casual office to a weekend hike.

Wrist Presence

3.5/5. The Kermit green dial is undeniably eye-catching, but the 39mm case and titanium finish keep it from being loud. It’s a conversation starter for those in the know, but it won’t scream for attention in a boardroom. The green rubber strap tones down the presence even further.

Reference Variants

The ProPilot X family includes blue (ref. 01 400 7778 7154-Set) and grey (ref. 01 400 7778 7155-Set) dial variants, both with matching rubber straps. The Kermit is the only green dial in the lineup.

Family and Other Models

Other notable Oris models include the Aquis Date (dive watch), Big Crown Pointer Date (heritage pilot), and Divers Sixty-Five (vintage-inspired diver).

Similar Watches

Competitors include the IWC Mark XX (titanium option, similar pilot aesthetic), Tudor Black Bay 58 (steel, dive bezel), and Grand Seiko SBGA413 (titanium, Spring Drive).

Homages

While no direct homages exist, the San Martin SN004-G offers a titanium pilot-style watch with a green dial at around $250.

Investment Value

MSRP is $3,500, and pre-owned prices range from $2,800 to $3,200. The trend is stable; this is not a limited edition, so don’t expect appreciation. But it holds its value well for a modern Oris.

Service Interval

Oris recommends service every 5 years, costing approximately $500. Independent watchmakers can service the Caliber 400, but authorized service ensures COSC recertification.

Pros and Cons

Pros: Lightweight titanium, in-house movement with 5-day power reserve, COSC accuracy, unique green dial, two-strap set.

Cons: No micro-adjust on clasp, 39mm may feel small, small date window, no quick-set date.

Final Verdict

The Oris ProPilot X Kermit is a superb everyday watch for the modern collector who values comfort, accuracy, and a touch of whimsy. Its titanium construction and in-house movement make it a serious tool watch, while the Kermit green dial adds personality. If you want a watch that stands out without screaming, this is it.
