Casio’s April 2025 China listing introduced the G-SHOCK DW-5610UU-3PRM as a collaboration with lifestyle aesthetic brand MondaySleepingClub. Its sleep theme is expressed through the strap, case-back logo and pillow-inspired presentation—not through a sleep-tracking feature. Casio listed it at CNY 790 and marked it sold out on the page when indexed.
What is the Casio DW-5610UU-3PRM?
The DW-5610UU-3PRM is a China-listed G-SHOCK collaboration with MondaySleepingClub. Casio described the brand as a lifestyle aesthetic label and said the collaboration brings its minimalist style and lifestyle concept together with G-SHOCK’s identity. The model appeared in Casio China’s April 2025 new-products listing. Casio’s April 2025 announcement
Is the DW-5610UU-3PRM a sleep tracker?
Casio’s collaboration announcement does not claim sleep tracking or any sleep-health function. The word “sleep” refers to the design and branding details Casio describes, so the announcement is not evidence that the watch measures sleep.
What makes this G-SHOCK sleep-themed?
- Strap: It is printed with the MondaySleepingClub brand phrase “Sleep Well, Stay Healthy.”
- Case back: It bears the collaboration brand’s logo.
- Packaging: Casio says the special package places the watch on a custom pillow to echo the sleeping theme.
These details are specified in Casio’s China product announcement; they describe a visual collaboration rather than a health function.

What are the watch’s specifications?
Casio’s detailed specification page available for this design family is for the standard DW-5610UU-3, not a separate PRM specification sheet. The figures below therefore describe that related base model and should not be treated as independently confirmed PRM-specific specifications.
