Hello!

I've already introduced this watch to you (here: click), but I took some new and better photos today, so I'm going to start another post and add a little more information about the watch and the movement.

This is my Zenith El Primero HW Chronograph, dating from the late 90s / early 2000s:

The 40mm x 11,5mm make the watch a perfect size IMO, and with no rotor, the movement and watch is thin enough to slip comfortably under a shirt cuff. The watch is water resistant to 100m.

The watch has a 420Z column-wheel chronograph movement:

The 420 and 420Z movements were the hand-wound versions in the El Primero 400 series of Calibers. According to Ranfft, the 420 was produced from 1994. The 420Z is a later version with some technical upgrades and was produced from 1998. A nice overview of the history of the El Primero chronograph and, in particular, the 420(Z) movement is here: click.

Without the automatic rotor, there's an unobstructed view of the beautiful 36000bph (5Hz) movement through the display case-back:

I hope you don't mind me posting photos of this watch a second time.

Cheers!
