This is a pilot watch reminiscent of iconic instrument-inspired timepieces like Sinn's 556.A and Bell & Ross watches. The case and bracelet are made of titanium, making it very light. It also features a high-performance Seiko VH31 movement with a sweeping second hand. Accuracy is ±20 seconds per month (less than 1 second per day).
