In a year where almost every wearable on the market is desperately trying to be an AI assistant, a fitness coach, or a second smartphone, G-Shock has collaborated with Coca-Cola to create something refreshingly simple. The GA-2100CC-3A doesn't track your heart rate, analyse your sleep or tell you how stressed you are. Instead, it strips things back to what makes a traditional watch appealing in the first place: distinctive design, durability and a bit of personality. I spent a few weeks with this 140th-anniversary collaboration piece, and here's my two bits on whether it's a genuine collector's item or just an overpriced branding exercise. Inside the box of the GA-2100CC-3A, you get the watch, the usual warranty cards, and the standard manual. However, thisG-Shockbegins the surprises right from the box by bringing this watch in an exclusive commemorative box modelled after a vintage Coca-Cola vending machine. From the exterior to the interior of the box, you are constantly reminded about the Coca-Cola partnership, which does make unboxing it a special experience, especially for a G-Shock fanboy or fangirl. The GA-2100 has become one of G-Shock's most recognisable designs, and it is easy to see whyCasiochose it for this collaboration. In terms of the actual design, the watch comes with a thickness of around 11.8mm and weighs just 51g. It uses a Carbon Core Guard construction that has allowed Casio to keep the watch slimmer without sacrificing its shock-resistant build quality. The bezel and strap of the watch use a green shade inspired by the iconicCoca-Colacontour bottle. Meanwhile, the dial uses red and other Coca-Cola-inspired tones. The resin strap on the watch seems durable and is lightweight enough that it doesn't interfere with your day-to-day activities. I have always struggled with wearing anything on my wrist for long periods. Watches, fitness bands and even rings tend to leave my skin itchy and irritated after a few hours. So I was genuinely surprised by the GA-2100. I wore it continuously for more than 10 days during a recent trek, including through some fairly long days, and didn't experience any irritation. That's obviously a very personal observation, but given how rarely I can wear a watch continuously, it was one of the things I appreciated most about the GA-2100. The highlight of this watch is the partnership with Coca-Cola, and there are plenty of Easter eggs to find here for a collector. For starters, the day indicator on the watch at 9 o'clock is shaped like a Coke bottle. The dial, meanwhile, comes with subtle bubble-like patterns to remind you of the fizz of Coca-Cola, and the red accents on the hour markers are perhaps an ode to the classic bottle caps of Coca-Cola. If that's not enough for you, even the back case of the watch comes with Coca-Cola branding in the shape of the classic bottle cap. As mentioned earlier, the GA-2100CC-3A uses Casio's Carbon Core Guard structure and is shock-resistant. It is also rated for up to
