Dufrane has made a habit of highlighting Austin, its history, and its surrounding area with their watches--the Bergstrom Air, the City Limits, and the aforementioned Barton Spring, are but a few. Founder Steven Lee has even chosen to hand assemble the timepieces in his adopted home. In the case of the Deep Eddy, that's an automatic Swiss movement and American assembly for under $500USD. Hard to beat.
Spinnaker does a good job of resurrecting obscure moments and personalities from the past to instil their pieces with character and flavour. The Croft Mid-Size references the 1967 accomplishment of a US Navy diving instructor by the name of Robert Croft--who became the first man to ever free dive beyond a depth of 200 feet. Ultimately, the vintage, skin-diver styling of the Croft, fit well with the man and the moment they are meant to celebrate.
I think it's officially okay to state that the 1970s have arrived...again. Their new herald? The integrated bracelet sports watch. Guy Roebuck, of the Roebuck Watch Company, has seen the future of dive watches and apparently it lies in the past. I tend to agree.
