The extremely durable Zulu strap, originally designed for military use, can take heavy-duty wear and tear and is widely trusted by professional divers. Easy to adjust on wetsuit but also comfortable on the wrist when not diving. The strap comes with two separate quick release pins and is easy to change without tools.
Suunto requires proof of being an instructor or divemaster to get the instructor blue color. Paperwork will sent to you after you place the order.
