Casio G-Shock DW-5600SRS-7 Resin

The Casio G-Shock DW-5600SRS-7 is a landmark entry in the DW-5600 lineage as the first-ever G-Shock to feature a full-surface gradated crystal finish, with rainbow vapor deposition applied to the mineral glass crystal across its entire surface to produce an iridescent multicolor effect that shifts and changes hue depending on the angle of light, evoking what Casio describes as the midsummer sky at dusk, with each individual unit producing a slightly unique color gradation pattern due to the nature of the vapor deposition process making this technically a one-of-a-kind timepiece. Built on the DW-5600’s classic square resin case measuring 48.9 by 42.8 by 13.4 millimeters with a transparent white tough resin case and matching transparent white high-durability resin band, the SRS-7 maintains the full G-Shock specification suite including shock resistance, 200-meter water resistance, electro-luminescent backlight with afterglow, 1/100-second stopwatch, countdown timer, multi-function alarm, hourly time signal, full auto-calendar to 2039, and 12/24-hour format, running on a CR2016 battery with approximately two years of life. The negative LCD display sits behind the iridescent crystal, which Casio notes may affect readability at certain viewing angles as a design trade-off inherent to the specially treated glass.The DW-5600 silhouette carries one of the most storied identities in watch culture, tracing directly to the original DW-5000C introduced in 1983 and adopted across decades of hip-hop, streetwear, and sport culture as the defining square G-Shock, and the SRS-7’s vapor deposition treatment elevates the utilitarian base model into a fashion-forward collectible that bridges the G-Shock’s functional heritage with the aesthetic experimentation of the brand’s Iridescent Color Series. The rainbow crystal’s light-interactive quality makes the watch behave differently across indoor and outdoor environments and across different times of day, giving a single watch multiple visual personalities depending on lighting context. At $125 retail the DW-5600SRS-7 represents a modest premium over standard DW-5600 pricing, reflecting the specialized vapor deposition process that Casio applies to produce the rainbow crystal finish.
