 For over 130 years each compass manufactured by E.S. Ritchie & Sons, Inc. was recorded by serial number in hand written ledgers. From the first liquid dampened compass to today's modern PowerDamp dial designs our Engineering Department has been critical to the development of the modern marine compass. Today, sophisticated computers and specialized instrumentation also allow Ritchie Navigation to develop better and more efficient ways to build compasses. |
