spring drive/grand seiko models in titanium: any diashield?
i've sort of fallen into the seiko brightz titanium hole, and now wish to upgrade from my SBDC007 to a grand seiko or spring drive made with the same material...



but i was trying to find out models (old and current) that feature diashield to no avail..



of the current models i found:



i know the SBDB001 (600m SD GMT) is titanium with no diashield.



the snowflake SBGA011 and SBGA031 are also titanium brightz without diashield.



not sure if there are any i left out...



are there any spring drive or GS models with diashield made in the past?



any input most welcomed!
