Historical Significance & Collectability:
The Zenith Caliber 106 was one of the brand’s most used and trusted movements. This is the much rarer version, the caliber 106-6. Known for its small seconds function and the incorporation of *Incabloc shock protection — a major innovation at The time — it combined reliability with mechanical elegance. (Read more on the Incabloc design below)
* What is Incabloc Shock Protection?
Incabloc is a type of shock-absorbing system developed in the 1930s by Swiss engineers to protect the delicate balance staff — one of the most vulnerable and critical parts of a mechanical watch movement.
The balance staff is a tiny axle that holds the balance wheel, which oscillates back and forth to regulate timekeeping. In early watches, any drop or impact could snap the balance staff, requiring expensive repairs or a full movement replacement.
The Incabloc system solved this by suspending the jewel bearings in a spring-mounted setting. When the watch experiences a shock — like being dropped or hit — the springs allow the jewel and staff to momentarily move and absorb the impact, then return to their normal position. This dramatically reduced breakages and made mechanical watches more durable for everyday wear.
Why It Matters for Collectors:
Historic Innovation:
In the 1940s and 1950s, incorporating Incabloc was a cutting-edge advancement. A watch like the Zenith Caliber 106-6 featuring Incabloc shows that it was built with modern durability in mind — a quality not all vintage pieces can claim.
Mechanical Integrity:
The presence of Incabloc improves the longevity and reliability of a vintage movement. It shows the maker invested in preserving the accuracy and resilience of the watch over time.
Collector’s Reassurance:
While still delicate by modern standards, a watch with Incabloc is generally considered more robust than its earlier counterparts — which means you can wear it with a bit more confidence (though vintage care is still essential).
Fun Fact:
The Incabloc system is easily identified by the small, lyre-shaped spring (often visible under a loupe on the balance jewel). It became an industry standard and is still in use today — a testament to its brilliant, simple engineering.
What makes this movement truly special today is its rarity: only 5,300 examples were produced (according to Ranfft), making it a coveted piece for collectors seeking both heritage and scarcity.
This watch is encased in a beautifully preserved solid 9K yellow gold case, made in Britain by Dennison, a revered casemaker who collaborated with Zenith during the post-war era when Swiss firms often sourced cases locally due to import restrictions. The result is a blend of Swiss precision and British goldsmithing — durable, handsome, and historically significant.
Design Feature: Teardrop Lugs – Art in Motion
What truly elevates this timepiece is its beautifully sculpted teardrop lugs — a rare and refined design element that evokes the fluid lines of Art Deco and early post-war style. These lugs don’t just connect strap to case — they transform the watch into a work of wearable sculpture, tapering elegantly from the case and curving slightly outward with subtle drama.
This design was reserved for more luxurious pieces of the time and is a favorite among vintage purists. It lends the watch a presence far beyond its modest 33mm case size, making it as much a piece of jewelry as it is a mechanical instrument.
A Watch That Tells More Than Time
Wearing this watch isn’t just about style — it’s about connection. Picture it on the wrist of a young professional in 1950s London, checking the time before catching a train under a gaslit sky. Or gifted as a milestone — a symbol of earned respect and quiet confidence.
Its warm golden tones, soft acrylic crystal, and subtle dial patina echo an era when every detail mattered. This is a timepiece that doesn't scream — it whispers legacy.

Final Thoughts for the Collector:
This is your opportunity to own a genuine piece of horological history — not a reissue, not a homage, but a true original. For collectors, enthusiasts, or those seeking a meaningful heirloom, the 1951 Zenith Caliber 106-6 offers enduring value, mechanical soul, and vintage charm that simply can’t be replicated.
Whether worn daily or reserved for special moments, this watch speaks with the quiet authority of a bygone era — and will continue ticking long into the future.
“A vintage timepiece doesn't just tell the time — it tells a story. It carries the heartbeat of another era, the quiet elegance of lives once lived, and the promise that true craftsmanship is never out of style.” -
