  • Control via AP™ 44, AP 48 or easily integrate with your Simrad® multifunction display
  • No need for an additional hydraulic pump, rudder sensor, or dockside calibration

NAC™ -D is a steer-by-wire autopilot solution for Electronic Vessel Control Systems (steering systems with a digital interface).

With NAC -D, boaters with SeaStar® Optimus®, Yanmar® VC10/JC10, Volvo® IPS/EVC or Yamaha® helm master/single engine control systems can benefit from all the full features and performance of Simrad® autopilots.

Requires only the connection of two Micro-C connectors — there is no requirement for an additional hydraulic pump, rudder sensor installation or dockside rudder calibration. This saves boaters’ time and money.

Featuring Continuum® steering and support for the new SteadySteer™, the NAC -D allows automatic switching between two speed profiles delivering optimal steering performance at both low and high speeds.

Choose the controller to suit your preference from dedicated controllers like the AP™ 44 or AP 48, or simply integrate with your Simrad® multifunction display.

Simrad® autopilot systems incorporate state-of-the-art electronics and represent over 70 years of experience and development. Simrad® autopilots can reduce your workload and fatigue and improve your situational awareness and safety, helping you arrive fresher at your destination.

Classic Craftsmanship That Keeps Perfect Time
This is an outstanding watch that blends craftsmanship, reliability, and timeless design. From the moment you put it on, it feels solid and well-built, with a level of precision that reflects true attention to detail. One important thing to understand is that this is a mechanical watch, not automatic, which means it requires manual winding. Personally, I wind the crown every morning—it’s become part of my daily routine and adds a certain charm and connection to the watch that you simply don’t get with battery-powered or automatic models. Once fully wound, the power reserve lasts around 24 hours, and impressively, the watch keeps extremely accurate time throughout. I’ve found it to be consistently reliable, rarely needing any adjustment. Rather than being an inconvenience, the manual winding becomes part of the experience—it’s a reminder of the craftsmanship behind the piece. If you appreciate traditional watchmaking and don’t mind a small daily ritual, this watch is truly exceptional.

Watch that's not a Speedy with its own 1970s racing heritage from the same group that owns Omega
Beautiful watch with its own heritage, yes it's at the upper end for a Tissot, but the high caliber movement used other brands like Omega and Longines as well as the superior fit and finish, justify the price of this watch.
