Product Details
Description
The Casio G-SHOCK GA-2100-1A1, affectionately known as the "CasiOak", is one of the most popular men's watches in the G-SHOCK Classics line. Its distinctive octagonal Carbon Core Guard case combines outstanding shock resistance with a surprisingly slim profile of just 11.8 mm. The hybrid analog-digital dial displays hours and minutes via classic hands, while the digital display handles the date, day of the week and additional functions — a clever combination that unites sporting character with excellent legibility.
The GA-2100-1A1 is water-resistant to 200 metres, making it suitable not only for everyday wear but also for swimming and snorkelling. The black resin strap with pin buckle sits comfortably on the wrist and fits wrist circumferences from 14.5 to 21.5 cm. With five daily alarms, a 1/100-second stopwatch, world time, countdown timer and automatic LED illumination, this watch is a reliable companion for sport, adventure and daily life.
