Casio Duro Marlin

MDV-106

Casio MDV-106 Blue

Introduced in 2011 this inexpensive quartz dive watch has 200m water resistance and was available in three colours, Black, Blue and Black/Gold and has a case size of 44mm.
The Casio Quartz 2784 has quickset date, hacking seconds, is accurate to +-20 seconds/month, and can last three years on its battery.
Originally supplied on a black rubber strap which is ideal for a dive watch with an option for a stainless steel bracelet, with a 22mm lug width there are plenty of options to customise your watch.

The MDV-106 'Marlin' is only available in the US, in the UK the model is the MDV-107 without the Marlin designation, this is due to licensing restrictions.

Casio recently released a ‘38mm’ version of the Duro, but the quality is not as good and the water resistance is only 50m

G-SHOCK

GWM5610U Square G-SHOCK

This model from the square-faced 5600 series features Multi-Band 6 technology and carries on the design legacy of the DW-5000C, which was born in 1983.
It inherits the classic case shape and dial design of the original DW-5000, giving it a timeless look.

Solar powered and Radio time sync makes it the most versatile watch.
