Sea‑Gull Panda Eye
A piece that came in for its panda-style dial and for a mechanism that is much less conventional than it first appears. The two sub-dials do not time a chronograph: they show the day of the week and the date, adjusted with the side pushers.

Why we bought it
More interesting up close
The silver dial with black sub-dials recalls a classic chronograph, but hides a complete, easy-to-read calendar. The exhibition caseback reveals the Sea-Gull ST25 automatic movement and makes the mechanics part of the piece’s appeal.
The watch arrived with box, manual, tag and leather strap with deployant clasp. We photographed both the set and the details that help explain its construction.
What happened next
Back in circulation
After documenting it, the watch found a new owner through Wallapop on 18 August 2026. This entry keeps its time with Reloj con Criterio as a record of a real operation, not as an out-of-stock product.

Analysis
ARTICLE / 01
Quartz or automatic?
Precision, convenience, mechanics and passion. Two different ways of understanding a watch, and a question we often ask the wrong way.
The question is not which is better. It is what you expect from the watch.
READ · 4 MIN
For years, a very simple hierarchy has taken hold: the automatic watch would be the authentic one and quartz a lesser alternative. But a movement does not make a piece interesting on its own. Design, construction, condition, reference and intended use matter just as much or more.
01 / QUARTZ
Precise, convenient and always ready
Quartz is usually more accurate, needs less attention and can spend weeks in a drawer before returning to the wrist without having to be set. For a daily, travel or beater watch, that convenience is not a compromise: it is a real advantage.
In return, the battery needs replacing from time to time and it offers less of the mechanical element many enthusiasts enjoy. In the secondary market, generic quartz watches also tend to need a particularly appealing reference, design or price to stand out.
02 / AUTOMATIC
Mechanics, ritual and passion
An automatic is powered by the movement of the wrist. Knowing that a set of wheels, springs and gears is working beneath the dial without a battery is part of its charm. Mechanics add conversation, ritual and, in many cases, a special connection with the piece.
It is also less accurate, stops after some time without use and can be more complex to service. Choosing one means accepting these small inconveniences because they are part of what we seek in it.
The secondary market
The movement does not sell the watch on its own
An unknown automatic is not automatically a good buy. And a sought-after quartz watch does not stop being interesting because it has a battery. Brand, exact reference, condition, contents, demand and entry price are the facts that decide whether a piece makes sense.
That is why we prefer to study each watch before applying a fixed rule. Judgement begins when we stop buying a category and start buying a specific piece.
There is no better one. There is one that is better for you.
Transparency, no small print
The good. And the bad too.
We do not try to make a watch look better than it is. We document its condition, signs of use, known defects, work carried out and available contents so you can decide with all the information.
