From the manufacturer

SIG SAUER ROMEO3MAX PRO Reflex Red Dot Sight 1x31mm 3 MOA Red Dot Black. The ROMEO3MAX PRO is the embodiment of a lifetime of repetition and experience in the competitive environment refined over tens of thousands of rounds to deliver the most dominant optic to date. Transitioning to the standardized PRO footprint the ROMEO3MAX PRO will mount directly to your favorite optics-ready pistol while maintaining an ultra-low deck height to optimize height over bore axis. SIG s industry-leading aspherical glass lens system provides a generous sight window with unrivaled clarity to expedite target acquisition and eliminate distortion. Available in either a 3 or 8 MOA red dot with 15 total illumination intervals the ROMEO3MAX PRO gives you the ability to fine tune brightness settings for any environment. Featuring an IPX-7 waterproof rating and 20000-hour runtime the ROMEO3MAX PRO is backed by SIG SAUER S Infinite Guarantee.

Dependable waterproof (IPX-7 rated for complete water immersion up to 1 meter) and fogproof performance. 20000 hour runtime from a common CR1632 battery (at medium brightness settings) in a side mounted tray meaning there is no need to remove the optic to change the battery.
