A sunburst watch dial can look surprisingly different from one moment to the next. Under direct light, the surface may appear bright and reflective, while a change in viewing angle can make the same dial look deeper and more subdued. This changing appearance comes from the way the dial surface interacts with light.
Also known as a sunray dial, a sunburst finish creates a directional pattern that catches and reflects light across the surface. Some watches take this effect further by combining the reflective finish with horizontal striped texture, creating a dial with more visual depth and character. The Shanghai Watch 7120 is one example of this approach.

Light on the Dial
The defining feature of a sunburst dial is its response to changing light. Fine surface lines reflect light differently depending on the angle of the watch, so the dial does not always appear as one fixed shade. This effect is particularly noticeable on darker colors such as blue, where brighter reflections can contrast with deeper areas of the surface.
This gives a sunburst dial a sense of movement without relying on elaborate decoration. Instead of looking completely flat, the surface changes subtly as the wrist moves or as the surrounding light changes. It is one reason sunray dials are commonly used on dress and everyday watches where the dial itself plays an important role in the overall design.
Texture Adds Depth
Horizontal striped texture can add another visual element to a sunburst watch dial. Rather than treating stripes and sunray finishing as competing styles, the two can be combined to create a more distinctive surface that becomes easier to notice under changing light.
A dark blue sunray horizontal dial offers a deeper, more expressive appearance, while a light sunray horizontal striped dial creates a softer look. On the light version, stud-textured hour markers and applied engraved hour markers add further definition to the surface.
A Vintage Influence
Sunburst dials also work naturally with vintage-inspired watch design. A heritage reissue can retain visual details associated with earlier watch styles while using contemporary materials and mechanical components.
A 39mm stainless steel case gives this type of watch relatively compact proportions, while a 10.95mm case thickness provides enough presence for everyday wear. The 316L stainless steel case is paired with a vintage-style 316L stainless steel exhibition case back, maintaining the overall connection between classic styling and modern construction.
A domed sapphire crystal completes the vintage-inspired profile while offering the scratch resistance associated with modern sapphire crystal.

Ready for Daily Life
A 39mm automatic watch can be a practical choice for someone who wants noticeable wrist presence without moving into larger case sizes. The compact diameter also works well with dressier and everyday styling, allowing the dial to remain the visual focus.
With 5 Bar water resistance, equivalent to 50 meters, this type of watch is intended for normal daily use rather than dedicated underwater activities. A date display adds another practical feature, while the stainless steel construction and sapphire crystal provide a durable foundation for regular wear.
Automatic Inside
The watch uses the Caliber 2130 automatic mechanical movement, with up to 42 hours of power reserve. It operates at 28,800 vibrations per hour, or 4 Hz, and contains 28 jewels.
For buyers interested in mechanical watches, the movement adds a traditional element beneath the dial-focused design. The combination of automatic winding and a relatively compact 39mm case makes the watch suitable for those looking for mechanical character without a large or overly complicated exterior.

Different Expressions: Blue & White
The dark blue version features a sunray horizontal dial paired with a stainless steel bracelet, creating a clean and structured look. The blue surface changes subtly with the light, while the metal bracelet reinforces the watch's more refined and traditional character.
The light version takes a softer approach with its light sunray horizontal striped dial and detailed hour markers. Its combination of textured dial elements, applied engraved markers and stainless steel construction gives the watch a different visual character while keeping the overall design understated and versatile.
Conclusion
Available for $479, the Shanghai Watch 7120 combines a 39mm 316L stainless steel case, domed sapphire crystal, automatic mechanical movement, date display and vintage-inspired design. The dark blue and light dial versions also offer different approaches to the same horizontal sunray concept.
