The community take
Owners widely praise the Casio GM-6900's forged metal bezel, with some noting the satin and polished finish on the silver variant and others appreciating the gold tone. The build is described as solid, with one owner finding the resin strap more comfortable than a bracelet and even more enjoyable than a Casioak strap. However, some reviewers and owners express disappointment that the GM-6900 lacks modern features like world time, solar power, or Bluetooth, and its overall size, particularly with the metal bezel, can feel large. The Casio GM-6900 series, featuring stainless steel bezels, weighs approximately 96 grams and has a Japanese list price range of 25,300 to 28,600 JPY, with US list prices from $180 to $230. On balance, owners and reviewers appreciate the GM-6900's distinctive metal bezel and improved strap comfort, though some wish for more modern functionalities.
