Singer J Balvin spotted wearing a Casio

Spotted on the golf course alongside DJ Khaled, Colombian reggaeton heavyweight J Balvin kept his wrist game deliberately low-key yet unmistakably intentional with the Casio G-Shock GA-B2100C-9AER in striking yellow resin — a choice that reads less as an afterthought and more as a studied streetwear statement from someone who owns watches at every price tier.

The GA-B2100C-9AER sits within the GA-B2100 family launched in 2021, itself a modern evolution rooted in the octagonal bezel aesthetic that traces back to the G-Shock 6900 series of the 1990s. The case measures 45.5 mm and is constructed around Casio's Carbon Core Guard architecture — a hollow inner resin skeleton that reduces weight while maintaining the structural rigidity required to meet G-Shock's 20-bar water resistance and shock-protection standards. The screwed stainless steel case back provides additional integrity. Power comes from Casio's Tough Solar system, which harvests artificial and natural light to keep the module charged indefinitely under normal use. Bluetooth Low Energy links the watch to a smartphone via the G-Shock Move app, enabling automatic time zone correction and precise timekeeping without manual adjustment.

The analog-digital display — a combination Casio calls 'Ana-Digi' — pairs a traditional hour-minute hand set with a digital LCD window for date, seconds, stopwatch and world time functions. It is a format G-Shock collectors associate with versatility, readable in both casual and active contexts. The GA-B2100 line has earned a strong following among younger collectors precisely because it delivers genuine smartwatch-adjacent connectivity and solar autonomy at an accessible price, without the compromises of a full fitness-tracker aesthetic.

For J Balvin, a self-declared watch enthusiast who has been photographed with everything from Richard Mille to custom Rolexes, the G-Shock GA-B2100C-9AER in yellow resin is a telling choice. The colour mirrors the maximalist palette that defines his visual identity — bright, confident, internationally legible. Wearing it on a golf course alongside DJ Khaled underscores that point: no dress code demands a high-complication piece when a sixty-dollar Casio makes the same statement with more personality.

At retail the GA-B2100C-9AER lists well under one hundred dollars, making it one of the most accessible watches in any celebrity sighting on record. Grey-market pricing mirrors retail closely given healthy supply, meaning anyone who wants Balvin's exact wrist look can replicate it without a waiting list or a broker.
