The Ball Engineer Hydrocarbon Submarine Warfare Chronograph is the Ultimate Explorers Watch, benefiting of exceptional resistance and exclusive patented innovations as a crown protection and the Amortiser anti-shock patented system. Avoiding that a shock creates sudden and violent oscillations of the rotor that can seriously spoil the movement.
I found Iguana really friendly, helpful and efficient to both buy the pen and when I had a query - very quick to respond. The pen is gorgeous and I’m now using it every day.
