SB04-E

Genesis

SARTORY-BILLARD crafts timepieces that are deeply personal, elevating bespoke watchmaking to an art form. Customization is at the heart of our evolution, empowering our clients to transform their visions into exquisite reality.

MAKE IT YOURS

Bespoke Dials

All the SB04-E watches are made to order and these elements can be refined for you: dials, hands finishes and 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 3500€ non-refundable deposit. When your watch is in production, we will ask for the balance payment.

Average budget SB04-E Bespoke project is 5500/6500€.
The delivery time is around 4 months.
The watch must be fully paid before shipping.

Options:
A vast selection of stones for dials, guilloché patterns, and unique materials to craft your watch.

ORDERING PROCESS

Hands

The hands are slender and feature diamond-cut edges, designed to catch and reflect light vividly, creating areas of brightness and shadow that give the hands a sense of depth and volume.

Both the hour and minute hands are linear brushed and are filled with BGW9 Super-LumiNova®, while the seconds hand includes a small polished tip, also diamond-cut for a brilliant finish. These hands interact dynamically with light, enhancing their elegance while subtly drawing attention to the beauty of the dial.

Options:
- Steel color hands or blued, with or without Luminova.

DESIGN GUIDE

Case & back case

The SB04-E bezel features a concave design that reflects light and its surroundings, creating an optical effect that visually reduces the watch’s thickness.

This design also brings the sapphire crystal—and consequently the dial—closer to the wearer’s eye, enhancing its beauty. The watch case alternates between polished and brushed surfaces, with chamfered and polished edges adding a refined touch.

A signature Sartory-Billard design element is the subtle separation between the short lugs and the main circular case. Combined with the concave bezel, these design features create an optical illusion of slimness, making the watch, which measures just over 10 mm in thickness, appear significantly thinner than it actually is.

Want a unique engraving to commemorate your bespoke SB04-E? Opt for the closed case back, where I can engrave a logo, date, quote, or any meaningful detail of your choice.

Options:
- Open case back – Showcases the movement in all its mechanical beauty.
- Closed case back – Ideal for a personalized engraving (logo, date, quote, or any meaningful detail).

Index disk

One of the defining features of the latest generation of Sartory-Billard watches, also present in the new SB04-E, is the sapphire disk onto which the hour markers are applied.

This sapphire disk features an inner ring made of metal, with a chamfered edge polished using a diamond tool, while the outer surfaces of the ring are circularly brushed.

The disk is adorned with even-numbered markers crafted from metal, with all visible surfaces polished with a diamond-cut finish.

The Super-LumiNova® BGW9 pad printed minute track and odd-numbered markers showcase the brand’s signature Y-shaped design, inspired by the Eiffel Tower—a nod to the founder’s Parisian roots.

At just 0.3 mm thick, the sapphire disk is treated with anti-reflective coating on both sides, allowing a perfect view on the minute dial beneath it.

Options:
- Sapphire disk with diamond cuts indexes.
- Metal cut Indexes without sapphire (like the former SB04 range).

Straps

Like all watches in the Sartory-Billard range, the 20 mm width lugs are drilled to accommodate curved straps.

Sartory-Billard Rubber : Designed for a perfect fit on your wrist and secured by a sleek spring-loaded deployment clasp, this watch strap offers exceptional durability and water resistance while being easy to maintain.

Options:
- Leather strap
