Nikon Introduces New MONARCH X Binoculars
February 18, 2009
Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to present the new MONARCH X binoculars, superior models in the globally popular MONARCH series. These new binoculars feature outstanding optical quality further enhanced by a large 45 mm objective diameter and innovative dielectric high-reflective multilayer prism coating.
The O-ring seals and nitrogen gas in the slim body make these binoculars waterproof and fog-free. Rubber coating protects the binocular body and assures a firm and conformable grip. The 8.5x and 10.5x MONARCH X binoculars are available for observing nature such as birds and other animals.

- All lenses and prisms are multilayer-coated for the brightest images
- Phase-correction-coated roof prisms for high resolution
- Waterproof (up to 1 m/3.3 ft. for 10 minutes) and fog-free with O-ring seals and nitrogen gas
- High-eyepoint design for clear field of view, even for eyeglass wearers
- Turn-and-slide rubber eyecups with multi-click facilitate easy positioning of eyes at the correct eyepoint
