De Bethune DB28XS Purple Rain (titanium)

Archive · used only

The De Bethune DB28XS Purple Rain (titanium) was a 38.7 mm Grade 5 titanium watch with a De Bethune DB2005 hand-wound movement. With a 144-hour power reserve, it runs longer than 97% of the 1,109 mechanical titanium watches with a stated reserve. At 7.4 mm thick, it is thinner than 94% of the 1,310 titanium watches with a stated thickness. On the maker's specification no steel touches the skin, so the guide lists it as nickel-free. It is no longer made, so this page is a reference for buying one used.

Frequently asked questions

Is the De Bethune DB28XS Purple Rain (titanium) nickel-free?

On the maker's published specification, nothing that touches the skin is steel: the case, caseback, crown and strap buckle are all non-steel. The guide records what the maker publishes and has not tested the watch, so if you react to nickel, confirm the contact points with the maker before buying.

What grade of titanium is the De Bethune DB28XS Purple Rain (titanium)?

Grade 5, from a secondary source. The guide has not yet read the grade on the maker's own page. The caseback is titanium too.

The case is 38.7 mm across and 7.4 mm thick. It is water resistant to 30 m.
