Two sets. Two for the price of one
New rubber watch band with pins, 19mm, great for your dive watch or sport watch, durable and easy to install. Great for swimming or hiking as to not ruin your leather band.
I also include the fitment pins, usually if you have a sport watch the pins are likley to corrod causing failure and potentially losing your watch the depths of the deep blue sea, it's good practice to replace the pins when you change the band.
