The Founder
Oussama
Aboulhassan
Collector. Curator. Founder of Vingtsecondes — where every vintage timepiece is chosen with the same obsessive care it was originally crafted.
"A watch does not merely measure time — it bears witness to it."— Oussama Aboulhassan, Vingtsecondes
Twenty seconds to fall in love.
A lifetime of knowledge
behind each piece.
Oussama Aboulhassan's passion for vintage watches began not in a boutique or auction house, but in the quiet study of horological history — turning case backs, reading calibre references, and learning to distinguish genuine patina from artificial aging. Over years of dedicated collecting, that curiosity became expertise.
Born and based in Morocco, Oussama built Vingtsecondes as the bridge he wished had existed when he started collecting: a curated, trustworthy source of authenticated vintage Japanese and Swiss timepieces for discerning buyers across the Moroccan market and beyond. The name itself is a nod to a simple truth — it takes exactly twenty seconds to know whether a watch speaks to you.
"Vingtsecondes exists because every great watch deserves a second life — and every collector deserves a seller they can trust."
From the iconic Seiko references of the 1960s–80s to rare Swiss chronographs bearing the marks of an era long past, each watch that enters the Vingtsecondes collection is personally sourced, authenticated, and presented with full transparency about its condition, history, and character.
This is not a marketplace. It is a carefully considered cabinet of horological objects — each one selected because Oussama himself would wear it.
Deep knowledge.
Deeper passion.
Six domains of expertise that define every decision made at Vingtsecondes.
Hands-on experience identifying genuine vintage references across Seiko, Swiss chronograph, and dress watch categories — reading dials, hands, movements, and case markings with a trained eye.
Specialist knowledge of Seiko's historical production — from the 5-series and vintage divers to early Grand Seiko references — including calibre identification, production dating, and reference variants.
Deep familiarity with Swiss ebauche movements, chronograph complications, and the makers behind them — Valjoux, Venus, Landeron — informing precise identification of unmarked or private-label pieces.
Rigorous, honest assessment of case wear, dial integrity, crystal clarity, and movement health — presented transparently so buyers know exactly what they are acquiring.
Continuous tracking of international collector markets — Chrono24, auction results, and specialist forums — ensures fair, reference-accurate pricing for every piece.
Every listing goes beyond specification sheets. Oussama tells the story of each watch — its era, its context, what makes this particular example worth treasuring.
The Journey
From collector
to curator
The Beginning
The First Watch
A chance encounter with a vintage Seiko ignites a fascination — not just with how watches look, but with how they work, who made them, and why certain references endure. The study begins.
The Education
Calibres, References & Patina
Years of hands-on research: dissecting movements, studying reference guides, connecting with the global collector community, and developing an instinct for authenticity that no database can fully replicate.
The Opportunity
A Gap in the Moroccan Market
Oussama identifies what is missing locally: a trustworthy, knowledgeable source for vintage timepieces — not grey-market speculation, but honest curation. The seed of Vingtsecondes is planted.
The Launch
Vingtsecondes is Born
Vingtsecondes launches — a curated online boutique bringing authenticated vintage Japanese and Swiss watches to collectors in Morocco and across the region, with every piece personally selected and described.
Today
Growing the Cabinet
The collection continues to grow — each acquisition a deliberate choice, each sale a relationship. Vingtsecondes is building a community of collectors who value knowledge as much as aesthetics.
The Standard
Every piece.
Personally vetted.
Oussama does not list watches he would not wear himself. It is a simple rule, but it changes everything — the sourcing criteria, the condition threshold, the honesty of every description.
At Vingtsecondes, the promise is not perfection — it is authenticity. Every flaw is documented. Every story is told. Every price reflects the true market and the true condition of the piece.
