The Sinn 103 Sa B E takes the familiar 103 chronograph and gives it a distinctive blue-and-ivory look, with a display back and a reported 500-piece production limit. In Robert-Jan Broer’s April 2018 hands-on, the appeal is chiefly visual: the core specifications remain close to those of the basic 103, while the dial, bezel and caseback make this edition feel different.
What makes the Sinn 103 Sa B E different?
The edition’s signature is its blue sunburst dial paired with a blue bezel. Ivory-colored hour markers and hands give the face a warmer contrast than the classic black 103. Broer describes the dial effect as “just mind-blowing,” a personal reaction rather than an objective measure of quality. The watch also has sapphire crystals on both the front and back, so the movement can be seen through the display caseback.
Those details distinguish the Sa B E without changing the basic character of the 103. The 2018 hands-on article says its main specifications are those of the basic model. The differences that matter most are therefore aesthetic and configurational: blue instead of black, ivory-tone luminous accents, a visible movement, and the edition designation.
How does it compare with the classic Sinn 103?
| Feature | Sinn 103 Sa B E | Classic Sinn 103 |
|---|---|---|
| Dial and bezel | Blue sunburst dial and blue bezel, according to Broer’s 2018 hands-on. Fratello Watches | The classic black version is the comparison identified in the 2018 article; further details are not stated there. Fratello Watches |
| Luminous accents | Ivory-colored markers and hands, according to the 2018 hands-on. Fratello Watches | Not stated in the source’s comparison. Fratello Watches |
| Crystal and caseback | Sapphire crystals on both sides, including a display back, according to the 2018 hands-on. Fratello Watches | Not stated in the source’s comparison. Fratello Watches |
| Core specifications | The 2018 article says the main specifications match the basic 103. | The 2018 article says the Sa B E shares the basic 103’s main specifications. |
| Edition and price context | Reported as limited to 500 pieces; Broer gave a €2,590 leather-strap retail price in April 2018. | Broer felt the standard 103 could offer better price/value for buyers choosing on specifications alone; this was his opinion based on 2018 pricing. |
For a buyer deciding by specifications alone, Broer’s 2018 view was that the standard 103 could offer better value. That is a period-specific opinion, not a current price comparison. The Sa B E makes more sense for someone who particularly wants its blue-and-ivory design and display back.

What does “limited to 500” mean?
Broer reports that the movement’s weight mass is marked “Eine von 500,” meaning “One of 500.” The marking is not a unique individual number: it identifies the watch as part of the edition rather than specifying its place in a numbered sequence. Broer also cautions that the inscription alone does not establish how many examples were actually produced. Treat 500 as the edition’s reported limit, not independently audited production data.

Should you choose the Sa B E?
The Sa B E is the more distinctive choice if the blue dial and bezel, ivory-tone accents and movement display are the reasons you want a 103. If you are choosing strictly by the platform’s core specifications, the 2018 article gives little reason to prefer this edition over the basic model, and Broer considered the standard 103 the stronger value at the prices then available. Current availability and pricing have not been verified, so a present-day comparison requires checking live listings.
