The quick answer.
Thorn Watches SHY027 39mm BB58 Vintage Diver Automatic Watch is a 39 mm diver watch at $164 after code SEBASTIANBASSOL (before code $169). We recommend it for a buyer looking for an affordable automatic diver with sapphire, a steel bracelet and a compact 39 mm case.
Why it belongs on the shortlist.
This is an unusually complete spec package at the listed price: Thorn pairs a Japanese NH35 with a 316L steel case, anti-reflective sapphire, a rotating bezel and a 200 m rating. We would shortlist it for someone who values those practical diver features in a vintage-scale shape, rather than paying more for a closer brand name or a larger case.
Why we like the specification at this price.
The SHY027 brings together the features we look for in a budget mechanical diver: a known NH35 automatic, sapphire instead of mineral glass, a steel bracelet and a 200 m stated rating. That gives the $169 list price a clear rationale. We would still treat the water rating as the manufacturer’s claim and use a qualified watchmaker for any pressure test after service.
A vintage footprint, with modern thickness.
Thorn lists a 39 mm diameter and 45.5 mm lug-to-lug, proportions that keep the watch more contained than many contemporary divers. The 13 mm thickness will remain noticeable under a cuff. Compare the span and height with a watch you already wear before ordering.
The exact variant needs a stock check.
The official product data marks the SHY027 variant available, but the product page also renders sold-out wording. Because those signals conflict, we cannot tell you that checkout will succeed. Verify the black-dial SHY027 and its price directly with Thorn before purchase.

Closest alternatives.
- Orient Mako 40 RA-AC0Q07V30B · $355 listed (2026-10-16): A more than twice-the-price automatic diver route with sapphire and a 200 m rating. Its 39.9 mm case is similar in diameter, but the leather strap and higher price make it a different value proposition.
- BODERRY Voyager S72 Cream: A lower-priced, different-purpose field watch if you want titanium, sapphire and a 100 m rating rather than a rotating diver bezel and 200 m claim.
Think beyond the diameter.
The published 45.5 mm lug-to-lug gives you a useful starting point for checking overhang. Use our wrist-fit guide and compare the proportions with a watch you already enjoy wearing.
