Introduction

The LOBINNI 16003 is a 41.5mm Seagull ST16K3-3A automatic dress watch — the most complication-rich Seagull movement in the LOBINNI range at Jewelry Addicts, combining moonphase display, world time city ring, week indicator, date window and 24-hour sub-dial. Guilloché-style textured dial with Roman numeral markers, sapphire crystal, 316L stainless steel case at 11.5mm with polished curved lugs, genuine leather strap with push-button hidden clasp, lion-motif engraved exhibition caseback, 50m water resistance. Six variants (P1–P6) across white and black dials with rose gold and silver case options.

Key Specifications

Variants — Six Configurations (P1–P6)

The six variants span white and black dials across rose gold and silver case options with brown and black leather strap combinations. Confirm the specific dial colour, case finish and strap for each P-code variant from the product listing images before selecting.

Seagull ST16K3-3A — Five Simultaneous Complications

The ST16K3-3A is the most feature-complete Seagull caliber in the LOBINNI range at Jewelry Addicts — five complications on a single automatic movement:

Moonphase: Shows the current lunar phase through a disc aperture — the moon disc advances incrementally as days pass. Manual correction required approximately every 2.5 years as the mechanical 29.5-day approximation accumulates a one-day offset.

World time: A city-name ring on the dial references multiple time zones — the button on the case side adjusts the world time display. This is a simplified world time complication showing city references rather than a full 24-city GMT mechanism, but provides a practical time-zone reference.

Week display: Shows the current day of the week.

Date window: Shows the current date (1–31).

24-hour sub-dial: Shows the current hour in 24-hour format for AM/PM reference.

The ST16K3-3A is significantly more complex than the ST16D used in the LOBINNI 16001 — adding moonphase and world time to the already comprehensive calendar functions.

Guilloché Dial Texture

The dial uses a guilloché-style textured surface — wave or radial engine-turned patterns across the dial field creating directional light scatter. The texture creates visual depth appropriate for the multiple recessed sub-dial zones. Applied Roman numerals at the hour positions provide formal dress character alongside the complication displays.

Lion Motif Exhibition Caseback

The exhibition caseback features an engraved lion motif on the inner or outer caseback ring — a decorative detail visible when wearing the watch while checking the movement. The movement itself is a Seagull ST16K3-3A automatic visible through the sapphire caseback window.

16003 in the LOBINNI Moonphase Range

The 16003 is one of two LOBINNI moonphase watches at Jewelry Addicts — alongside the 17015 Engravers Meteorite which uses Shanghai JHB10 with a crescent moon display. The 16003 is the more mechanically specified moonphase — ST16K3-3A with world time and the full calendar set.

16003 vs Other LOBINNI Seagull Calendar Models

The 16003 is the most complicated Seagull-caliber LOBINNI in the range.

Who Is the LOBINNI 16003 For?

The 16003 is built for:

• Moonphase automatic buyers who want Seagull in-house with world time alongside the moonphase — the most complicated LOBINNI at this price
• World time reference buyers who want the city-name ring display on an automatic dress watch under $200
• Guilloché dial buyers who want the textured wave or radial surface on a multi-complication dress watch
• LOBINNI buyers who want the maximum complication depth in the brand’s Seagull movement range

How It Compares

vs. AGELOCER Astronomer Moonphase — AGELOCER uses Cal.A4610 in-house at 40mm/11mm with 3D sculpted 28.5mm panoramic moonphase and 80-hour reserve. LOBINNI uses ST16K3-3A at 41.5mm/11.5mm with smaller moonphase but adds world time, week, date and 24-hour. Choose AGELOCER for the dominant moonphase display and 80-hour reserve; choose LOBINNI for the world time and broader calendar set.

vs. Seagull 816.423 Moonphase — Seagull uses ST21 with moonphase + power reserve + pointer date at 40.5mm on steel bracelet. LOBINNI uses ST16K3-3A with moonphase + world time + week + date + 24-hour at 41.5mm on leather. Both are Seagull in-house moonphase automatics — different additional complications and strap types.

vs. LOBINNI 16001 Seagull ST16D — 16001 has month + day + date + 24-hour but no moonphase or world time. 16003 adds moonphase and world time to a similar calendar base.
