This is a SCUBAPRO CHROMIS diving computer. I purchased it in September 2014 and have used it for about 75 dives over 11 years. I've been using it as a secondary computer for the last two years. The battery was replaced on August 27, 2025. I haven't dived with it since the battery replacement. When the battery was replaced in June 2023, the strap and buttons were worn, so I replaced them. I have never used the extension strap. The screen has never been cracked because I used a protector. The included accessories are the instruction manual, the system disc (unopened), and the extension strap. The warranty card has the store name on it, but the warranty has expired as it was a 2-year warranty. Please note that there are minor scratches due to years of use. ◆ Immediate purchase is welcome! ◆ I do not accept price negotiations or changes to the shipping method. ◆ I will pack the item as carefully as possible, but I may use recycled cardboard boxes. Some items may be simply packaged. Please read the above notes. If you have any questions about the item, feel free to comment. #SCUBAPRO #Scubapro #Spro #S-Pro #CHROMIS #Chromis #Diving #DiveComputer #DivingComputer #DiveComputer
