This is my good ol Seiko Professional dive watch, which was given to me on my 15th birthday by Kohei. At 15, it looked ridiculous on my scrawny teenage wrist, but now, 9 years later, that has been upgraded to "slightly too large". This thing is a tank, more a bludgeon than a timepiece. It can withstand great pressures, safely able to dive down as far as 200 metres without danger of implosion. This is my new watch of choice while teaching at my hoikuens and shogakkos, as even they won't be able to harm it.
