Jacob & Co. introduced the Astronomia Solar Dragon in 2025 as a hand-wound, animated watch centred on a hand-sculpted dragon. The 44 mm watch was announced in 18k rose gold and black DLC-coated titanium, with the titanium edition limited to four unique pieces. Its vertical JCAM42 movement combines a one-minute flying tourbillon with a magnesium Earth globe that rotates once per minute.
What is the Astronomia Solar Dragon?
The Solar Dragon is part of Jacob & Co.’s Astronomia line, known for presenting moving components in an open, sculptural display. In this 2025 release, a hand-sculpted dragon sits close to the movement’s arms above a titanium baseplate decorated with a star map. The construction is shown beneath a domed sapphire crystal and sapphire caseband, according to Monochrome Watches’ 2025 launch report.
Monochrome reports that the rose-gold dragon is cast in three solid pieces, then engraved, polished and hand-painted. The titanium editions receive a black DLC coating. These are design and finishing details reported for the launch, not independent assessments of durability or performance.

How the movement and animated display work
The hand-wound JCAM42 is arranged vertically to make the movement’s orbiting display part of the watch’s visual centrepiece. Its reported functions include a one-minute flying tourbillon and a magnesium globe representing Earth, which rotates once per minute. The time is shown on a skeletonised off-centre display. Monochrome Watches reports 296 components, a frequency of 28,800 vibrations per hour and a 48-hour power reserve for this movement.
The one-minute rotation describes the globe’s motion; it should not be mistaken for a claim about timekeeping accuracy. No independent accuracy or performance test results were established in the cited launch coverage.

Rose gold or black DLC titanium?
The two announced case options share the reported 44 mm by 21 mm dimensions and 30 m water resistance. Their key distinctions are the case and dragon treatment, plus the titanium edition’s unusually small, individually varied run.
| Edition | Reported details | Production |
|---|---|---|
| 18k rose gold | Rose-gold case; dragon described by Monochrome as cast in three solid pieces, engraved, polished and hand-painted | 36 pieces, according to Monochrome Watches’ 2025 launch report |

Do not confuse it with the Astronomia Dragon
The Astronomia Solar Dragon is distinct from Jacob & Co.’s related Astronomia Dragon. Jacob & Co.’s official Japanese Astronomia Dragon page identifies that other model with calibre JCAM25, 384 components, a 60-hour power reserve, a double-axis tourbillon and a 50 mm case. Those figures belong to the Astronomia Dragon, not the Solar Dragon. The official Japanese Astronomia collection price catalogue likewise lists other Astronomia Dragon references and does not establish a Solar Dragon price.
Price and availability
Monochrome Watches reported the Solar Dragon’s price as “upon request” in its 2025 launch coverage. A current retail price, live inventory or verified marketplace listing was not established. With only 36 rose-gold pieces and four unique titanium examples reported at launch, availability should be checked against the specific edition rather than inferred from the announcement.
