Two 6139-6002’s Wearing Their Original Bracelets

The yellow dialed version is an early one from July 1969 and the silver dial, made I believe for the Australian market only, is from April 1973. ...

It’s a nice pair!

Two pieces of history! Best, Emmanuel

Thanks, Emmanuel. The reference does have a great deal of history behind it. It's still in question whether Seiko beat the Swiss/Zenith to introduce the first automatic chronograph movement in 1969!

Both of those are nice and look great on the wrist. I’m drawn to the silver dial.

Thanks Larry. The silver is quite special, and likely more unique than the yellow version!

I am losing track of your Seikos—but you are building an awesome collection!

Love the yellow dial version!!

Thanks Ron! I am definitely on a vintage Seiko kit. I'm sure there will come a day when I will ask myself why I bought so many! But for now, let the obsession continue!

A nice duo, Rob, I'm partial to the fine-looking silver dialed version !
