ISO 200m water-resistant yellow FROGMAN, digital display. - Model Name: FROGMAN DW-8250Y-9T - Color: Yellow - Water Resistance: ISO 200m - Price: ¥24,000 This is the DW-8250Y FROGMAN, a model with enduring popularity. The bezel has hydrolyzed, so a brand new, unused GF-8250 bezel has been installed. Therefore, I think you can use it without worrying about hydrolysis for the foreseeable future.
