The ST16D is a Seagull in-house automatic caliber with complete calendar complications — day, date, month and 24-hour display all driven from a single movement. This is the most function-rich Seagull caliber in the LOBINNI range at Jewelry Addicts, significantly more complex than the ST2130 (date only) used in the 12026.
Day/week display (left window): Shows the current day of the week. Date window (right): Shows the current date (1–31). Month sub-dial (top): Shows the current month (JAN–DEC). 24-hour sub-dial (bottom): Shows the current hour on a 24-hour scale for AM/PM reference.
Calendar adjustment: The side pushers on the case allow independent correction of each calendar function — essential for the end of short months (February, April, June etc.) where the month display requires manual advancement.
Applied three-dimensional Arabic numerals at the hour positions create visual depth — each numeral is a separate metal piece attached to the dial surface, casting a slight shadow at its base. The raised numerals on a complete calendar dial create a specific traditional European watch character, associating legibility with formal dress.
Both the 16001 and the 16013 are multi-function LOBINNI automatics with extensive calendar displays. Key differences:
| Feature | 16001 (this page) | 16013 Miyota 9122 |
|---|---|---|
| Movement | Seagull ST16D in-house | Miyota 9122 |
| Functions | Day + date + month + 24-hour | Week + month + date + tachymeter |
| Numerals | Raised Arabic | Mixed Arabic + markers |
| Case | 41.5mm | 42mm |
| Pushers | Yes — calendar adjustment | Confirm |
Choose 16001 for Seagull in-house movement, raised Arabic numerals and full month display with adjustment pushers. Choose 16013 for Miyota 9122 with tachymeter scale and the angular case design.
The 16001 is the most complication-rich Seagull-movement LOBINNI at Jewelry Addicts:

| 12026 Business | Seagull ST2130 | Date only |
| 816.423 Moonphase | Seagull ST21 | Moonphase + power reserve + pointer date |
