The Schwarz Etienne ASE 200 is an in-house automatic micro-rotor caliber reported in watches including the Roma Synergy, Fiji Floral Seconds and Havid Nagan HN000. Published details point to an 86-hour power reserve in cited examples, while a 3 Hz frequency is specified for one Fiji Floral Seconds configuration. Construction and finishing depend on the particular watch and caliber version.
What is the Schwarz Etienne ASE 200?
Phillips describes the caliber in the Roma Synergy as Schwarz Etienne’s in-house movement; WatchTime also identifies the ASE 200 as an automatic micro-rotor movement. A micro-rotor is integrated into the movement rather than placed above it as a full-size rotor, allowing the movement to retain an automatic winding system in a more compact arrangement.

The name appears in more than one watch context: the Roma Synergy, Schwarz Etienne’s Fiji Floral Seconds, and the Havid Nagan HN000. The sources refer to specific versions, including ASE 200.00 and ASE 200.M1. The base designation alone does not establish that every model has identical construction, decoration or specifications.
Published ASE 200 specifications
| Specification | What the cited source reports |
|---|---|
| Winding and rotor | Automatic micro-rotor movement, as described for the Fiji Floral Seconds by Manfredi Jewels and La Cote des Montres. |

| Rotor and movement finish | Phillips describes the Roma Synergy’s 4N gold-plated micro-rotor as sitting flush with the bridges. WatchTime reports dark NAC treatment alongside traditional decorative finishing on the HN000 version. |
These figures are reported for cited watches, not established here as universal specifications for every ASE 200 variant. The available references are editorial and retailer sources; they do not provide an official manufacturer technical sheet covering the caliber family.

How the caliber differs across cited watches
Roma Synergy
Phillips describes a 4N gold-plated micro-rotor integrated flush with the bridges and reports an 86-hour power reserve for this Roma Synergy caliber. Those details describe the cited watch rather than every movement carrying the ASE 200 name.
Fiji Floral Seconds
Manfredi Jewels lists the Fiji Floral Seconds with an ASE 200.00 and an 86-hour reserve. La Cote des Montres identifies a 3 Hz frequency for the Fiji Floral Seconds Joaillerie description. Keep those figures tied to their respective product references rather than assuming every Fiji or ASE 200 model shares them.
Rank #2
- Wall-to-wall mineral crystal lens
- Glossy black dial with genuine diamond at 12; rose gold-tone hands and markers
- Black ceramic adjustable link bracelet; jewelry clasp and extender
- Water resistant to 100 feet (30M)
- 33mm round rose gold-tone case; Wall-to-wall crystal with black dial frame
Havid Nagan HN000
WatchTime identifies the HN000 as using an ASE 200.M1 and notes a dark NAC treatment combined with traditional decorative finishes. This illustrates that appearance and finishing can vary by model or collaboration even when the movement family is shared.

The caliber name is only one part of a watch specification. Before comparing models or listings, confirm the exact reference and suffix, then check the details that determine how the watch wears and functions:
Rank #3
- 22mm petite case; 0.87" diameter
- Floral shaped dial cover accented with 109 clear premium crystals; mirror on underside of cover
- Champagne sunray dial with gold-tone hands and markers
- Gold-tone stainless steel mesh bracelet with adjustable end links; jewelry clasp and extender; inner band circumference 6 3/4"
- Water resistant to 100 feet (30M)
- Exact caliber version: Look for the full designation, such as ASE 200.00 or ASE 200.M1, rather than relying on “ASE 200” alone.
- Functions and complications: Confirm what the dial displays and whether the chosen version adds functions beyond timekeeping.
- Case and practical specifications: Compare dimensions, case material and water resistance for the specific watch.
- Finishing: Check whether the listing describes a gold-plated, dark-treated or otherwise finished rotor and movement.
- Ownership terms: Verify current availability, price, warranty and service arrangements with the seller or manufacturer.
The cited sources do not provide a consistent, complete specification set across all three watches, so they are not enough to make a quantified performance comparison between models.
