Product Details

Originally created to assist with flight planning, the slide rule can calculate speed, distance, flight time, and fuel consumption, and convert miles to kilometers.

Designed for pilots and loved by enthusiasts, the Navitimer is defined by its notched bezel and circular slide rule.

Shipping and returns

Orders are usually prepared within 1–3 business days after confirmation. Weekends and public holidays are excluded; business hours are counted during normal operating days, not continuously. Estimated transit after dispatch is 3–5 business days. Preparation and transit are separate periods. Carrier delays, remote locations and exceptional conditions can extend estimates; delivery dates are not guaranteed.

Our voluntary return window is 60 calendar days after delivery for eligible unused items. Contact us before sending a return. Product-specific exclusions must be disclosed before purchase; mandatory consumer rights remain unaffected.
