SB04s Bespoke – 37 mm

The Same. Smaller.


The SARTORY-BILLARD “SB04s” is an exquisite timepiece that offers a refined and extended experience for those seeking a smaller and thinner wristwatch option. As the 37mm variation of our popular model, the 40mm SB04, it caters specifically to individuals with slimmer wrists who value both style and comfort. Contrary to the common notion that smaller versions of products are downgrades, the SB04s is in no way inferior to its larger counterpart. It carries all the exceptional qualities and meticulous craftsmanship that define our brand.

Which case size is right for you ?

We have ensured that every detail receives the same bespoke attention, ensuring that its smaller size does not compromise the overall experience. The 37mm case of the SB04s not only accentuates elegance but also provides a perfect fit for those with thinner wrists. The reduced dimensions allow for a more proportionate and balanced appearance, enhancing the overall aesthetic appeal. Additionally, the slender profile of the watch ensures a comfortable wearing experience throughout the day.

Despite its smaller size, the SB04s retains all the benefits and features that have made our SB04 model so sought after. It boasts exceptional accuracy, durability, and precision, as well as a host of other functionalities that our customers have come to expect from our timepieces.

At SARTORY-BILLARD, we understand that personal preferences and individual styles vary, which is why we have designed the SB04s to cater specifically to those with thinner wrists. It is a testament to our commitment to providing timepieces that not only meet the highest standards of craftsmanship but also consider the diverse needs and preferences of our discerning customers.

In conclusion, the SARTORY-BILLARD “SB04s” is an exquisite 37mm wristwatch that offers the same exceptional quality and bespoke attention as its larger counterpart. It is a perfect choice for those with thinner wrists who seek a timepiece that combines style, comfort, and the unrivaled craftsmanship that defines the SARTORY-BILLARD brand.


All the SB04s watches are made to order and these elements can be refined for you: dial, numbers, indexes design, hands finishes, case finishes, strap.

As we talk about the watch you wish to own, I create renderings of your design until the style is the one you desire. To seal the project I ask you for a 2500€ non-refundable deposit. When your watch is in production, we will ask for the balance payment. The delivery time is around 6 months. The watch must be fully paid before shipping.
