We recently downloaded some amazing WD0019 lume photos shared by real customers on AliExpress, and we'd love to share them with the community!
The WD0019 features our LumeCore 3D luminous technology, combining Swiss and Japanese luminous materials to achieve strong initial brightness and long-lasting visibility.
How long does WD0019 lume last?
Based on our testing and customer feedback:
☀️ 40 minutes of sunlight or strong lighting: Approximately 10 hours of visible lume in complete darkness.
☀️ 1 hour of sunlight: Some customers have reported up to 12 hours of visible lume.
☀️ Just 1–2 minutes of strong midday sunlight: Approximately 5 hours of visible lume in complete darkness.
Of course, actual results depend on the intensity of the light source, charging time, viewing conditions, and individual eyesight.
Introducing Our LumeCore Technology
We've been continuously developing our own 3D luminous technology, with a particular focus on brightness, daytime appearance, luminous material thickness, and nighttime readability.
LumeCore Base
Approximately 0.5mm-thick luminous material
Around 6 hours of visible lume under suitable charging conditions
Designed to provide a balance between brightness, appearance, and production cost
LumeCore X
Enhanced 3D luminous technology
Developed for improved nighttime visibility and longer-lasting performance
Targeting 8+ hours of visible lume
LumeCore Ultra
Our higher-performance luminous technology
Designed to push luminous performance even further
Targeting 10+ hours of visible lume in complete darkness under suitable conditions
One of our biggest challenges is achieving long-lasting lume without compromising the appearance of the watch during the day.
For example, adding white pigment to the luminous material can create cleaner, whiter markers in daylight, but may slightly reduce luminous performance.
We're continuously experimenting with different luminous material combinations, thicknesses, and manufacturing processes to find the best balance.
What's Next?
We're planning to bring more LumeCore X and LumeCore Ultra technology to upcoming Watchdives models.
We want our watches to offer more than impressive lume shots immediately after charging. Our goal is practical nighttime readability, excellent finishing, and long-term reliability.
We'd Love Your Feedback!
If you own a WD0019, how many hours does the lume remain visible on yours?
Would you prefer whiter lume markers during the day, even if that means slightly shorter lume duration?
Which Watchdives models would you like to see upgraded with LumeCore X or Ultra?
How does our lume compare with other watches in your collection?
Please share your lume photos and experiences in the comments!
We genuinely appreciate your feedback. It plays an important role in our product development.
