Tourbillon Essentials: A Beginner’s Masterclass
Learn to compare date displays, GMT, power reserve, flying, central and dual tourbillons, with verified examples from Hong Kong tourbillon brand Memorigin.
The first tourbillon worth considering is one you will enjoy wearing. Begin with how the watch sits on your wrist, how clearly you can read it and whether you enjoy its design after the first fascination with the rotating cage has passed.
Start with the mechanism and the fit
Check that the watch has a genuine rotating tourbillon carriage. Then compare manual or automatic winding, power reserve and the position of the display. A longer reserve can be convenient, but it does not on its own demonstrate better finishing or greater accuracy.
Case shape matters as much as a diameter figure. A cushion case and a round case with similar numbers may feel quite different. Try the watch where possible and ask how the strap or bracelet can be fitted. Leave room in the budget for appropriate servicing and any applicable delivery taxes.
What changes as prices rise?
A useful starting point is a straightforward flying tourbillon in a steel case. Moving beyond it, the price may reflect a different movement architecture, a GMT or calendar display, more difficult case construction, extensive hand finishing, sculpted dials, gemstones or bespoke work.
These are different kinds of value. A gem-set dial may take considerable skill without adding a mechanical complication. An automatic winding system adds a mechanism but is not automatically more expensive than every manual design. Judge what has actually changed, rather than treating the price ladder as a simple count of functions.
Date displays: useful detail, different mechanisms
A date display adds a calendar reading to the time. A large-date display makes the numerals more prominent; it is a display format, not a claim that the calendar adjusts itself. Annual and perpetual calendars are different mechanisms and should never be assumed from the presence of a date window. The Explorer lists a date indicator. Before choosing, check how the date is read and corrected, and follow that movement’s setting instructions.
Look at how the date reading shares the dial with the time and tourbillon. An everyday feature is useful only if you can find and read it comfortably; the photograph is a way to judge the layout, while the product specification confirms the calendar function.
GMT and day/night: reading a second time zone
GMT and dual-time displays help the wearer follow another time zone; a day/night indication helps distinguish its morning and evening. A moon-phase display follows the lunar cycle and serves a different purpose. Stellar Imperial lists an Earth-sphere GMT indicator. Here the sphere belongs to the time-zone display: it is not a spherical tourbillon carriage.
On Stellar Imperial, the sculpted globe and the tourbillon are visually distinct elements. Looking at each separately makes the terminology clearer: a spherical display can describe a time-zone indication without describing the shape or axes of the regulating mechanism.
Power reserve, indicators and twin barrels
Power reserve is the approximate running time available from a fully wound watch. A power-reserve indicator is a separate display showing the remaining energy; a quoted reserve does not by itself mean that an indicator is fitted. Crescent Moon lists 48 hours of reserve. Twin mainspring barrels describe the energy-storage arrangement, not two tourbillons, and do not automatically mean twice the running time. Consider winding habits and the model’s actual specifications together.
Iron Man Tourbillon offers a useful comparison: its specification lists 80 hours of power reserve, twin mainspring barrels and a power-reserve indicator. That makes the distinction visible—a running-time specification tells you the capacity, while an indicator lets you follow the remaining energy.
Flying tourbillon: how the carriage is supported
A flying tourbillon is supported from below, leaving its upper side free of a supporting bridge. The term describes its support architecture; it does not mean automatic winding or rotation about several axes. Harmony of Dragon and Phoenix lists a flying tourbillon and automatic winding as separate characteristics. The attraction includes the open view of the mechanism, rather than a guaranteed advantage in accuracy.
Central tourbillon: bringing the mechanism to the centre
A centrally positioned tourbillon places the rotating carriage at the centre of the dial, so the surrounding hands and display require a different arrangement. The Six Steeds in the Tang Dynasty Tourbillon Watch is a documented example. “Central” here describes placement, not the number of rotation axes. Judge the clarity of the time display and the composition of the whole dial as well as the spectacle of the carriage.
The Six Steeds model puts the mechanism at the visual centre of the watch. Notice how this changes the relationship between the tourbillon and the surrounding display. It is a question of placement and dial design, rather than evidence of additional rotational axes.
Dual, bi-axial and multi-axis are different ideas
Dual Tourbillon Series has two tourbillon assemblies at 9 and 12 o’clock. Two assemblies do not make a bi-axial tourbillon: bi-axial describes rotation about two axes, while multi-axis refers to more than one axis. A spherical shape alone does not establish either arrangement. The current product descriptions reviewed for this guide do not identify a Memorigin model as bi-axial or multi-axis, so those terms are not assigned to these watches. Likewise, a bi-directional automatic-winding mechanism is not a bi-axial tourbillon.
In the Dual Tourbillon Series photograph, identify the two separate tourbillon assemblies before comparing the rest of the dial. Two visible mechanisms are not the same engineering proposition as a single mechanism rotating about more than one axis.
How should a Hong Kong tourbillon be compared with a Swiss watch?
Compare the particular watches, including origin, movement, finishing, case material, dimensions, documented performance and service arrangements. Swiss tourbillons span different price levels; it would be misleading to suggest they all begin at the same very high threshold. A lower price also does not establish identical finishing or performance.
For context, one current direct-sale Swiss tourbillon listing checked for this guide was CHF9,990. That is a model-specific reference, not the Swiss market’s minimum or an exchange-rate-adjusted saving. Taxes and included services must also be compared before drawing a conclusion.
Starting points from Memorigin
Hong Kong tourbillon brand Memorigin combines in-house movement development and production capability with its own design team. Bringing those disciplines together supports an approach to accessible tourbillon ownership, alongside more elaborate commissions and specialist projects.
The following are current listed examples, not a ranking of quality or a promise of immediate stock:
| Around HK$20,000–30,000 | Crescent Moon HK$19,800; Genesis HK$23,800. Crescent Moon is among the most accessible general-collection tourbillons in the current catalogue. Its manual movement offers 48 hours of reserve. |
|---|---|
| Around HK$30,000–60,000 | Marvel Series Iron Man HK$38,800; The Explorer HK$48,800; Stellar Imperial HK$49,800. Their differences include character-led design, a meteorite dial, automatic winding and a globe-shaped GMT display; each watch has its own combination. |
| Above HK$60,000 | Harmony of Dragon and Phoenix HK$66,800 brings a sculpted cultural scene to the dial. At a very different level, MEMOIRE’s Aspirare is listed at HK$688,000. Its Swiss Koncept collaboration, founded by watchmakers Kaj Korpela and Costya Vigneri, illustrates a distinct development and finishing project rather than a typical entry purchase. |
Design can be another reason to choose. Memorigin’s work with Mark Lui on The Time Machine, and its Marvel and Transformers collaborations, shows how the same interest in mechanics can meet very different creative worlds. A Swiss development partnership or a licensed character design describes that project; it does not make every watch Swiss-made or mechanically identical.
Choose the reference that fits your interests, then confirm its current price, configuration and preparation arrangements with the team.
