AGELOCER Astronomer Moon Phase Watch — Cal.A4610, 80-Hour Reserve, 3D Moon, 40mm

AGELOCER Astronomer Moon Phase Watch — Cal.A4610, 80-Hour Reserve, 3D Moon, 40mm

The AGELOCER Astronomer is a 40mm Cal.A4610 automatic moon phase watch — AGELOCER’s in-house self-winding caliber with 80-hour power reserve, 27 jewels, Incabloc shock absorption and Geneva stripe finishing. A 28.5mm panoramic moon phase display with a sculpted 3D metal moon surface, platinum-plated hands and indices, night-sky textured dial, 30mm sapphire exhibition caseback, crocodile-pattern cowhide leather strap with folding clasp and 50m water resistance. Eight variants across the 6401 and 6404 model families.

Key Specifications

Variants — Eight Configurations

The Astronomer uses a model number system combining dial family (6401 or 6404) with strap/case designation:

6404D9, 6404A9, 6404D2, 6404A1: The 6404 family — one dial configuration in multiple strap and case material combinations (D = steel case, A = likely alternate case finish; numbered suffixes indicate strap colour or case tone variations).

6401D9, 6401A9, 6401D2, 6401A1: The 6401 family — an alternative dial configuration with the same strap/case combination structure.

Confirm the specific dial colour, case finish and strap colour for each model number from the AGELOCER product pages or from Jewelry Addicts product images before selecting — the letter/number suffix system encodes specific configuration combinations.

Cal.A4610 — AGELOCER In-House Movement

The Cal.A4610 is AGELOCER’s own automatic caliber — not a Miyota, NH35 or Seagull movement. AGELOCER is a Swiss-influenced Chinese microbrand that designs and specifies its own movement architecture. The Cal.A4610’s key distinguishing specifications:

80-hour power reserve: More than three days of running from a full wind — consistent with the Hangzhou 80-hour range and significantly above the standard 40–42 hour automatic. For a watch primarily worn in formal contexts (business, events) rather than daily, the 80-hour reserve means the watch is still running after a weekend of non-wear.

27 jewels: Above the standard 17–21 jewels in most NH35/Miyota automatics. Additional jewels reduce friction at the pivot points that receive the highest rotational loads.

Incabloc shock absorption: A specific shock protection system — the balance staff pivots are spring-mounted in Incabloc holders that absorb impact without transferring it to the fragile pivot tips. Standard in Swiss mechanical production; less common in Chinese calibers at this price.

Geneva stripe finishing: Parallel linear decorations across the movement bridges — the same finishing technique as the Farasute XK-009A’s Côtes de Genève. Visible through the 30mm sapphire exhibition caseback.

Moon Phase Complication

The moon phase display shows the current phase of the lunar cycle — from new moon through waxing crescent, first quarter, waxing gibbous, full moon and back through waning phases. The 28.5mm panoramic display is unusually large for a 40mm watch — most moon phase complications at this dial size allocate 8–12mm to the moon disc.

3D sculpted metal moon: Rather than a flat printed disc, the Astronomer uses a three-dimensional metal moon surface — the lunar landscape is sculpted into the disc, creating depth and shadow effects under light. The 3D moon creates a more realistic and jewellery-like appearance than flat-printed equivalents.

Accuracy: Moon phase complications in mechanical watches require manual correction approximately every 2.5 years (the mechanical 29.5-day lunar cycle approximation accumulates approximately one day of error over this period). This is standard across all mechanical moon phase watches regardless of price.

11mm at 40mm

At 11mm the Astronomer is a slim mechanical moon phase watch — appropriate for dress and formal wear without the case height that automatic movements with complex complications sometimes require. The 82g weight reflects the slim case and leather strap.

AGELOCER at Jewelry Addicts

AGELOCER has multiple models at Jewelry Addicts — the Baikal, Codex 3302A1 and Schwarzwald alongside the Astronomer. The Baikal review has the strongest CTR in the AGELOCER range — buyers who appreciate the Baikal’s character will find the Astronomer covers the moon phase complication specifically.

Who Is the AGELOCER Astronomer For?

The Astronomer is built for:

• Moon phase buyers who want AGELOCER’s in-house Cal.A4610 with 80-hour reserve and 3D sculpted metal moon at 40mm
• In-house movement buyers who want a proprietary caliber with Geneva finishing and Incabloc shock protection rather than a bought-in NH35 or Miyota
• Formal occasion buyers who want a moon phase complication on an 11mm dress watch with platinum-plated hands
• Collectors who want the most mechanically specified moon phase in the under-$500 category

How It Compares

vs. Sugess M199S ST1908 Chrono Moonphase — The Sugess uses Seagull ST1908 with column-wheel chronograph + moon phase at 42mm. The AGELOCER Astronomer uses Cal.A4610 in-house with moon phase only at 40mm — choose Sugess for the chronograph complication alongside moon phase; choose AGELOCER for the 80-hour in-house reserve and 3D moon disc.

vs. OUPINKE 3189 Plamont Moonphase — The OUPINKE uses Plamont automatic with full calendar (day/date/month/moonphase). The AGELOCER Astronomer focuses on the panoramic 3D moon display as its primary complication with 80-hour in-house reserve.

vs. Farasute NL-007M Full Calendar — The Farasute uses Seagull automatic with full calendar but no moon phase. The AGELOCER has moon phase but no full calendar — different complication priorities.
