VETTA Chronomatic 

 

Caliber Chronomatic 12 

Hamilton-Buren, Breitling and Heuer

module Dubois-Depraz 8510 on Buren 1281

 

A Watch born out of the 60s & 70s Love of Motor car racing rivalry and the quieter arms race and rivalry of watch companies to produce the first automatic chronographs. 

The Vetta Takes the style of the sports rally watches and the engine of the swiss chronograph revolution. 

 

An altogether quieter company but this Vetta brings to the table italian style with a swiss heart

THE DIAL 

"Chronomatic's"  may well come in a variety of shapes sizes and indeed styles. But few if any are quite as stylish and unreservedly funky as the Vetta example listed today. 

50 shades of blue! 

 

A watch that never fails to get a second glance perhaps one of the most "picked up" watches on customer visits. 

 

This is a Rally chronograph note the tachymeter scale on the dials perimeter in blue coloration with with crisp white detail 

A layer in and we have the classic heavily detailed "Railroad" track seconds white background and black detail.
