Inercy is out with its new Compass collection, bringing a fresh take on the field watch with three distinct models. These watches center around a symmetrical thirty-nine-millimeter dual-crown steel case, featuring an internal solar compass bezel.
All three watches share the same core architecture. They use a thirty-nine-millimeter 316L stainless steel case, just ten millimeters thick. This makes them versatile for daily wear, sliding under a cuff while still having presence. The defining feature is the dual crown layout, reminiscent of vintage compressor divers. One crown sets the time, and the other operates the internal bidirectional bezel, which combines a minute track and a solar compass. Buyers can even configure the watch to have the time-setting crown on either the right or left side.
Powering each Compass model is the Swiss-made La Joux-Perret G101 automatic caliber. This movement provides a sixty-eight-hour power reserve, meaning you can take the watch off on Friday and it'll still be running Monday morning. It runs at four Hertz, or twenty-eight thousand eight hundred vibrations per hour, which helps with shock stability. Inercy fits it with a custom oscillating weight visible through the sapphire display back.
The collection includes three versions. The Inercy Compass Light features a pure white finely grained dial with high contrast, emphasizing legibility. It costs two thousand forty-nine dollars and is a limited edition of one hundred fifty pieces, shipping with both leather and rubber straps.
The Inercy Compass Dark is the classic tool watch expression, with a deep black grained dial. It also costs two thousand forty-nine dollars, is limited to one hundred fifty pieces, and comes with two straps.
Finally, the Inercy Compass Chocolate offers a distinct look with a finely grained chocolate brown dial and gold-toned PVD accents. This version was originally a special prize and was put into production due to collector demand. It is priced slightly higher at two thousand one hundred sixty-four dollars and is also a limited edition of one hundred fifty pieces, shipping with a single brown nubuck leather strap.
Each watch offers one hundred meters of water resistance, suitable for daily use and recreational swimming.
Inercy Compass: 39mm Dual-Crown Swiss Field Watch — watch the reel or listen to the full narration.
The new Inercy Compass collection is built around a single, focused idea: a modern field watch defined by perfect symmetry. The 39mm steel case features dual crowns at 3 and 9 o'clock, one controlling a Swiss automatic movement and the other operating an internal solar compass bezel. It’s a design that packs in functionality without compromising a clean, instrument-like profile.
The series launches with three distinct models sharing the same core architecture: the high-contrast Compass Light, the classic Compass Dark, and the warm-toned Compass Chocolate. Each is powered by the La Joux-Perret G101 caliber, offering a 68-hour power reserve.

3 Gold cards are randomly hidden inside the boxes of the 300 COMPASS watches in this edition: if you discover one upon delivery, the watch is yours.
All three watches are built on an identical technical base. The 316L stainless steel case measures 39mm in diameter by just 10mm thick. These dimensions position the Compass as a versatile daily-wear piece, thin enough to fit under a cuff while maintaining a solid presence.
The case’s defining feature is its dual-crown layout. The crowns sit opposite each other at 3 and 9 o'clock, creating a balanced look reminiscent of vintage compressor divers. One crown handles time-setting and winding, while the other operates the internal bidirectional bezel. In a unique touch, buyers can configure their watch to have the time-setting crown on either the right or left side.
That internal bezel, or *réhaut*, combines two functions under the sapphire crystal. It features both a minute track for timing short events and a solar compass for basic orientation. This keeps the watch’s external lines clean while adding genuine utility for outdoor use.
Powering the Compass: The La Joux-Perret G101
Inside each Inercy Compass is the Swiss-made La Joux-Perret G101 automatic caliber. This movement provides a substantial 68-hour power reserve, which the brand calls "Weekend-Proof." You can take the watch off on a Friday evening and it should still be running on Monday morning.
The G101 operates at a modern frequency of 4 Hz (28,800 vibrations per hour), which contributes to its stability against shocks. It’s a robust workhorse chosen for durability, and Inercy outfits it with a custom-designed oscillating weight visible through the sapphire display back.
This choice of a high-spec Swiss engine from a respected third-party specialist is a strategy we've seen from other independents in the circa-$2,000 price range. Yema, for example, recently used its own CMM.10 manufacture caliber in the new Superman Bronze CMM.10 Trio, prioritizing in-house credentials and a 70-hour reserve. Inercy's use of the G101 delivers a similar performance target from an established Swiss supplier.
Dial Details and a Unique Seconds Hand
The dial layout remains consistent across the collection. Tapered Dauphine hands for hours and minutes are filled with white Super-LumiNova for low-light legibility. A finely grained texture gives the dial surface a matte, non-reflective quality.
The seconds hand is a standout detail. It's a double-ended design that looks like a compass needle, with one tip painted red. To create this balanced form without straining the movement, Inercy machines the hand from ultra-lightweight aluminum. This reduces the torque required to move it, helping to maintain the movement's timekeeping stability.
Each watch ships with two straps: a black taurillon nubuck leather strap and a perforated black FKM rubber option. A custom pin buckle with grained, polished, and brushed finishing to match the case is included.
Inercy Compass - Light
The Compass Light presents the most direct, instrument-focused aesthetic of the trio. Its finely grained dial is pure white, creating high contrast against the black markings of the internal bezel and the dark handset outlines. This execution emphasizes legibility above all.
Priced at $2,049.00 USD, the Light model adheres to the core technical specifications of the Compass line. The bright white dial is framed by a circular metallic groove that adds depth and separates the main dial from the outer track. This version is a limited edition of 150 numbered pieces.
Like the other models, it comes with both leather and rubber straps, making it adaptable for city wear or outdoor activity. The 100-meter water resistance rating provides more than enough protection for daily use and recreational swimming. Any dialhead will appreciate the clean, functional design.
The Compass Chocolate is the most distinct variant in the collection. It features a finely grained chocolate brown dial paired with gold-toned PVD accents. According to the brand, this version was originally intended only as a special prize and was put into production due to collector demand.
It carries a slightly higher price of $2,164.00 USD and is offered as a limited edition of 150 numbered pieces. Unlike the other models, it ships with a single brown nubuck leather strap. The warm tones give the technical design a completely different character, shifting it from a pure tool watch to something with a more vintage-inspired feel.
The Compass Dark is the classic tool watch expression of the design. It uses a deep black, finely grained dial that provides a strong backdrop for the white Super-LumiNova on the hands and markers. This is the most traditional and tactical look of the three.
Priced identically to the Light model at $2,049.00 USD, the Dark version is also a limited edition of 150 numbered pieces. It shares the same 39mm steel case, La Joux-Perret G101 movement, and 100-meter water resistance rating as the rest of the family.
This model embodies the core concept of an understated adventure watch. Its symmetrical case and stealthy dial color make it a versatile choice, while the red-tipped seconds hand adds a subtle flash of color against the monochrome palette. It is delivered with both the black nubuck and black FKM rubber straps.
The Inercy Compass collection offers a distinct take on the modern field watch, centered on its symmetrical 39mm dual-crown case and integrated solar compass. With a robust Swiss automatic movement providing a 68-hour power reserve, it is positioned for enthusiasts seeking a thoughtfully designed and functional mechanical watch from an independent brand.
Frequently Asked Questions
What movement does the Inercy Compass use?
All models in the Inercy Compass collection use the Swiss-made La Joux-Perret G101 caliber. This is a mechanical movement with automatic winding, a 68-hour power reserve, and a frequency of 28,800 vph (4 Hz).
How does the solar compass work?
The internal bezel includes cardinal direction markers. To use it in the Northern Hemisphere, you point the hour hand at the sun. The midpoint on the dial between the hour hand and the 12 o'clock marker is South. You can then rotate the internal bezel via its dedicated crown to align the "S" with this position, giving you a rough bearing for all cardinal directions.
What is the difference between the Light, Dark, and Chocolate models?
The core specifications are identical. The differences are aesthetic and in edition size. The Light has a white dial and the Dark has a black dial, both limited to 150 pieces for $2,049 and including two straps. The Chocolate has a brown dial with gold PVD accents, is limited to 150 pieces, costs $2,164, and comes with one brown nubuck strap.
Can I choose which side the crowns are on?
Yes. Inercy allows customers to configure the watch during purchase. You can choose to have the time-setting crown on the right (3 o'clock) or left (9 o'clock), and the internal bezel crown will be placed on the opposite side.
Is the Inercy Compass a dive watch?
No. While it has a water resistance rating of 100 meters (10 ATM), which is suitable for swimming and recreational water activities, it is not a dedicated dive watch. It lacks features like a unidirectional dive bezel and the higher water resistance ratings (200m+) required for scuba diving.
