The Vostok Europe N1 Rocket Chrono is a rather large diving chronograph. Many sites list it as 46mm, but with the crown guard this beast is 49mm. Including the crown that figure jumps to almost 52mm. A lot of timepieces with a dive bezel are all bezel and little dial, the N1 chrono has 38mm dial. This black on black model is super desirable and with the 7 piece bracelet it’s comfortable too!

Original Model

This is the original model with the Miyota JS06 movement. You might notice that the newer reference 6S30/2255177 has a Miyota 6S30 giving it a different dial layout. On this piece, the subdials are smaller and has the following configuration: running central seconds, small chronograph seconds at 6:00, 30 minute chronograph counter at 10:00, 24 hour hand at 2:00.
