Ressence TYPE 2 Review: The Oil-Filled e-Crown Oddity
A mechanical watch that sets itself — but does it hold value?
Introduction
Ressence doesn't make watches for people who want to blend in. The Belgian independent has spent the last decade rethinking what a mechanical watch can be, and the TYPE 2 is its most audacious statement yet. It pairs a traditional automatic movement with an oil-filled dial and a self-setting 'e-Crown' that syncs the time via Bluetooth. The result is a watch that looks like nothing else on the wrist and behaves like a smartwatch in one very specific way.
For the trust-fund-baby collector, the TYPE 2 is a flex of a different kind. It's not about brand recognition or heritage — it's about signaling that you're deep enough into horology to appreciate a watch that costs $42,500 and still uses a base ETA movement. The question is whether that flex holds up when it's time to sell.
In this review, we'll break down the TYPE 2's specs, how it wears, what it costs to own, and whether it's a hold or a flip. Spoiler: it's not a flip.
Manufacture History
Ressence was founded in 2010 by industrial designer Benoît Mintiens in Antwerp, Belgium. The brand's name is a portmanteau of 'renaissance' and 'essence,' and its core innovation is the ROCS (Ressence Orbital Convex System), which replaces traditional hands with rotating discs submerged in oil. The oil eliminates refraction and makes the dial appear to be printed directly on the crystal.
The TYPE 2, launched in 2018, adds an electronic e-Crown that automatically sets the time via a smartphone app. It's a mechanical watch with a digital convenience, and it remains one of the most unusual propositions in modern horology.
Movement
The TYPE 2 uses a base ETA 2824-2 automatic movement, modified with Ressence's in-house ROCS 2 module. The base caliber is a workhorse, but the module adds 11 jewels and a complex gear train to drive the oil-filled rotating discs. Total jewel count is 36. Power reserve is 36 hours, and the frequency is 28,800 vph. The watch is not COSC certified, and the movement is not fully in-house — the base is ETA, but the module is proprietary.
The e-Crown is a separate electronic module that harvests kinetic energy from the rotor and can adjust the time via a small motor. It pairs with a smartphone app to set the time automatically, or you can tap the crystal to cycle through settings. It's a clever solution to the problem of setting a watch with no traditional crown.

Lug-to-lug is not officially published, but the short, downward-curving lugs keep the watch from overhanging on smaller wrists.
Wrist Feel
The TYPE 2 wears surprisingly well for a 45mm watch. The grade 5 titanium case is featherlight, and the absence of a traditional bezel means the dial dominates the wrist without feeling bulky. The 12mm thickness is moderate, and the curved caseback hugs the wrist. The oil-filled dial creates a unique visual effect — the numbers and hands appear to float directly on the crystal, with no visible gap. It's a conversation starter, but not uncomfortable for all-day wear.
The leather strap is supple and the pin buckle is simple. Overall, it's a watch you forget you're wearing until someone asks about it.
Accuracy
The base ETA 2824-2 is a known quantity, typically running within +/- 10 seconds per day. The ROCS module adds some friction, but Ressence regulates each watch before delivery. In practice, expect +/- 15 seconds per day. The e-Crown can correct the time automatically when paired with the app, so daily drift is less of an issue than on a traditional mechanical watch.
Occasions and Wrist Presence
The TYPE 2 is best suited for daily wear, dress occasions, and travel. It's not a sports watch — 30m water resistance means no swimming. Wrist presence is 4/5: not flashy in the traditional sense, but the oil-filled dial and rotating discs draw eyes immediately. It's a watch for people who want to be noticed by other watch nerds, not by the general public.
Reference Variants
The standard production model is the TYPE 2 in grade 5 titanium with a black oil-filled dial and leather strap. Limited editions with blue or grey dials have been released in small numbers, but they are hard to find and command a premium on the secondary market.
Family and Other Models
The TYPE 2 sits alongside the TYPE 1 (simpler, no e-Crown), TYPE 3 (larger, with date), TYPE 5 (dive watch), and TYPE 8 (smaller, more affordable). Other notable models from Ressence include the TYPE 9, a recent release with a more compact case.
Similar Watches
If you're considering the TYPE 2, you might also look at the MB&F Legacy Machine Perpetual, HYT H1, Urwerk UR-100, or De Bethune DB28. All are independent brands with radical approaches to time display, but most are significantly more expensive.
Investment Value
The TYPE 2 has an MSRP of $42,500, and current retail is the same. Pre-owned examples typically sell for $25,000 to $35,000, meaning the watch depreciates 20-40% the moment you walk out of the boutique. The trend is depreciating, and there is no major auction history to suggest a turnaround. If you must have one, buy pre-owned. It's a hold for personal enjoyment, not a flip.
Service Interval
Ressence recommends service every 5 years, at a cost of approximately $1,200. The oil-filled dial requires factory service, and the brand has a limited network of authorized service centers, so expect to ship the watch to Belgium.
Pros and Cons
Pros:
- Unique oil-filled dial with floating display
- e-Crown auto-setting via Bluetooth
- Lightweight grade 5 titanium case
- Avant-garde design that stands out
Cons:
- High price for a base ETA movement
- Low water resistance (30m)
- Limited service network
- Depreciates significantly on secondary market
Final Verdict
The Ressence TYPE 2 is a horological oddity that rewards the curious and punishes the impatient. It's not a value proposition, but it's a genuine piece of independent watchmaking that you won't see on every wrist. If you have the means and the desire to own something truly different, buy it pre-owned and enjoy the ride.
