Sunnto D4 / D4i नोवो डाइविंग वॉच सिलिकॉन वॉच बैंड एक्सटेंशन स्ट्रैप के साथ (काला)

First use and the pins in the strap have already started rusting. The spring mechanism pops under a slight knock so just be wary. The strap is also a little short for my wrist so it requires the additional extension when in a wetsuit which is a little annoying as it's easily forgotten. The original Suunto D4F strap could fit my wrist without using any extension both with and without a wetsuit.

However for the price, it's not a bad product. This is my second one so far, just look after it
