Status
Retired. Absent from aristo-uhrenvertrieb.de's (the maker's) full 1,088-URL product sitemap, which carries no reference 5H91 or hand-wound titanium Sextant listing (the sitemap's only Sextant is ref 3H78A, a stainless steel automatic, a different watch); only ever sold through the dealer site (aristo-shop.de), which this catalog's own 2026-08-25 verdict already treats as not the maker.

Is the Aristo Sextant 5H91 nickel-free?

On the maker's published specification, no nickel-bearing steel touches the skin: a titanium case with a titanium caseback, plus a non-steel crown and strap. That is what the guide records rather than a test of the watch, so confirm the contact points with the maker before buying if you react to nickel.

It is 38.4 mm in diameter, 9.6 mm thick, and water resistant to 100 m.

How much does the Aristo Sextant 5H91 cost, and is it available?
