The Disassembly and assembly of the Suunto quick-release coupler is best done with the Suunto quick-release tool.
 
The tool can be used to open the coupler by hand or if it is heavily corroded you can use a 14 mm open-end spanner, socket, or adjustable spanner wrench.
 
The Suunto quick-release tool is made from stainless steel with hardened stainless steel pins.
