New from OMEGA is the OMEGA Speedmaster's 3570.50.00, 3870.50.31, 3573.50.00 & 3873.50.31 replacements. The changes are as much as a new box which includes two different styled Nato watch straps. One traditionally style Nato strap and the other a replica of the Nato straps used by Astronauts on Space missions as they fit over their spacesuits. Also included in the new package are some tools. You will now receive a Speedmaster loupe and a Speedmaster strap changing tool along with strap changing instructions. OMEGA also include a Speedmaster coin and a book detailing the Speedmaster chronology.
