What is a Perpetual Calendar?
The perpetual calendar remains one of the greatest achievements in watchmaking, a symbol of human ingenuity and artistic refinement.


Selling or trading a valuable watch has never been easier. Between specialized platforms like Chrono24 , watch forums or sales between individuals, the market is fluid, international… and yet, one link remains dramatically underestimated: insurance during shipping .
Every year, thousands of sellers discover too late that relying on a carrier's basic insurance can turn a successful sale into a complete loss. Lost, stolen, or damaged watches, paltry compensation… The mistake is costly, but avoidable.
When a package is entrusted to a carrier, many sellers believe they are "automatically" covered. In reality, this coverage is very limited , especially when it comes to watches.
Most carriers, such as Chronopost , DHL , or UPS, apply the following:
low compensation limits , unrelated to the actual value of a watch,
explicit exclusions concerning luxury watches,
or vague conditions making reimbursement virtually impossible in the event of a dispute.
The result: a watch sold for several thousand euros may only be compensated for a few hundred, or even nothing at all. A false sense of security that doesn't hold up in the face of a real incident.
The problem often stems from a misunderstanding about the declared value . Declaring a package is not the same as actually insuring it. In many cases, the value is only indicative and does not obligate the carrier to pay compensation up to that amount.
This also applies to:
a Rolex Submariner,
an Omega Speedmaster
or even a collector's Seiko .
In the event of loss , theft , or damage during shipping, carriers' terms and conditions suddenly become very strict. Watches are often considered a high-risk category, subject to exclusions or caps, especially for pre-owned watches.
Faced with these limitations, experienced professionals and collectors have adopted a different approach. To truly ensure the safe shipment of watches , they use a specialized solution: Secursus .
Secursus has established itself as the leading insurance provider in the sector , used by watch dealers, platforms, and discerning collectors. Unlike insurance offered over the counter, Secursus operates on a simple and transparent principle: Ad Valorem .
In concrete terms:
The watch is insured for its declared actual value .
up to €100,000
including for second-hand watches,
without exclusion related to the brand or type of watch.
Another key advantage: Secursus is compatible with all standard carriers , both in France and internationally. You choose your usual carrier, and Secursus takes care of the coverage.
Contrary to popular belief, specialized insurance is not more expensive. Quite the opposite.
The insurance policies offered directly by the carriers are often:
30 to 50% more expensive ,
less well covered,
and accompanied by numerous restrictions.
Secursus optimizes its model by focusing solely on insurance, eliminating unnecessary intermediaries. The result: better coverage at a lower cost , making it an economically sound solution for shipping valuable watches.
Last but not least, simplicity. Secursus was designed to integrate seamlessly into the sales process:
100% online subscription,
in a few minutes,
without unnecessary paperwork,
valid for sales between individuals as well as for transactions via Chrono24.
In a context where security and trust are essential, especially with large sums of money involved, having clear and effective insurance is no longer an option, but a standard.
Protecting a watch during transport is essential, but security doesn't end with delivery. Once the transaction is finalized—or when it comes to preserving a collection—the question of secure storage becomes just as crucial.
More and more collectors are now opting for watch safes with integrated winders , which combine burglary protection, preservation of the automatic movement, and optimal storage of valuable timepieces. It's a sensible solution for those who consider their watches not as mere objects, but as horological heritage to be preserved.
Selling a valuable watch isn't just about finding a buyer. It also means taking responsibility for its delivery to its destination. Carriers' basic insurance, often misunderstood, unnecessarily exposes both sellers and buyers to significant losses.
Conversely, choosing a specialized insurance like Secursus allows you to secure each shipment, protect the real value of the watch and sell with complete peace of mind.
Today, for savvy sellers, ensuring the shipment of watches with a dedicated solution is no longer a luxury — it's a reflex.
The perpetual calendar remains one of the greatest achievements in watchmaking, a symbol of human ingenuity and artistic refinement.
