The five essential systems — energy source, gear train, escapement, oscillator, display — explained from first principles.
Automatic vs manual winding: what's the actual difference?
The rotor that winds itself, the ritual of hand-winding, and why neither is objectively better.
How a quartz watch works
The piezoelectric crystal that oscillates 32,768 times per second, and why it keeps time better than almost any mechanical movement.

The complete anatomy of a watch: every part explained
From the crystal to the caseback, the crown to the bracelet — a visual glossary of every component and what it does.
Understanding the dial: indices, hands, and text hierarchy
Why dial design is harder than it looks, and what separates a great dial from a merely competent one.
Case shapes and their history
Round, cushion, tonneau, rectangular, asymmetric — the major case forms and the watches that defined them.
Bracelets, straps, and the lug-width mystery
Everything you need to know about fitting, swapping, and choosing the right strap for any watch.

Deep dives into the components that make a mechanical watch tick.
4 articles
The escapement: the soul of the mechanical watch
The lever escapement, the detent escapement, and the silicon revolution — how watchmakers control the release of energy.
The balance wheel and why frequency matters
Why a watch ticking at 36,000 bph is more accurate than one at 18,000 bph — and the tradeoffs involved.
Côtes de Genève, perlage, and anglage: the art of movement finishing
The decorative finishing techniques applied to movements that no one will ever see — and why watchmakers still do it.
How to read a movement: what to look for through the caseback

Talking Watches With John Mayer
The first John Mayer Talking Watches with Hodinkee is where talking about watches really started for me. It made collecting feel less like flexing and more like storytelling, with Mayer bringing real taste, curiosity, and emotion to every piece. Enjoy.

About

Hey, I'm Michael AbouJaoude.

I've always been passionate about watches — the craftsmanship, the history, and the endless rabbit hole that comes with it. The combination of engineering, design, history, and pure technological achievement is what makes this the best hobby in the world, and honestly, it's hard to argue otherwise.

That passion is what led me to create The Horologue: a resource and reference for anyone on their horological journey, whether you're just starting out or you're a seasoned collector looking to go even deeper on your knowledge.

The Horologue also features Explore and Purchase sections — both personally curated by me. Explore is filled with content I genuinely think is worth your time, and Purchase is a collection of pieces I'd love to buy for myself if my wallet had a different opinion of me. In a world of infinite references and finite funds, going deeper on the craft is the ultimate flex.

Glad you're here. There's always more to discover.

Say hello

I read every message, though I cannot always reply promptly. If you have a correction, a question, a suggestion for something that should be covered, or just want to talk about watches — I am glad to hear from you.

Corrections

If you have found an error — factual, technical, or typographical — please do tell me. I take accuracy seriously and will correct mistakes promptly. Being wrong in print is embarrassing; being wrong in print and refusing to correct it is worse.
