This is a Casio Marlin, but it is not digital! The "Marlin" branding was used on analogue watches from the "MD" series as well for analogue diver watches. This is the MDV-100 watch, it is a Japanese equivalent to the "Duro" watch. It is very high quality and heavy! I think that it could be used to break a window! The dial also has a beautiful texture of water! This example is actually quite worn, but the watch is still working perfectly, so it is durable!
The watch has been checked for function and is working properly and keeps good time. The battery has been replaced. The case and the strap have been cleaned thoroughly. Due to age of the device we cannot guarantee same waterproofing as when new. Please proceed with caution.
