Aristo Sextant 5H91
The Aristo Sextant 5H91 was a 38.4 mm titanium pilot watch with a Sellita SW215 hand-wound movement. At 9.6 mm thick, only two of the 87 other titanium pilot watches with a stated thickness are thinner. At 38.4 mm across, it is smaller than 95% of the 108 titanium pilot watches in the guide. 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.

- 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.

Frequently asked questions
Is the Aristo Sextant 5H91 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 Aristo Sextant 5H91?
Titanium, with no grade stated. The caseback is titanium too. The record is at medium confidence, so check the maker's page before relying on it.
What size is the Aristo Sextant 5H91?
The case is 38.4 mm across and 9.6 mm thick. It is water resistant to 100 m.
How much does the Aristo Sextant 5H91 cost, and is it available?
It is no longer made, so the only way to buy one is used. Its list price when it was in production was $648.
