- AUTOMATIC: these self-winding, automatic men's watches are powered by your movement, with a power reserve of 41 hours
- STAINLESS STEEL GOLD FINISH: features a durable stainless steel watch case and bracelet with luxurious gold finish and see-through caseback

- Crystal and case back: Hardlex crystal and a display case back.
- Bezel and lume: unidirectional rotating bezel and LumiBrite on the hands and indexes.

- Water resistance: 100 m.
These are specifications reported in launch coverage, not independent measurements or comparative test results. A 20 mm lug spacing makes 20 mm straps a reasonable category to investigate, but it does not establish universal fit: check end-link clearance and the strap’s construction for the specific watch.
What 100 m water resistance does—and does not—mean
The models have a dive-inspired appearance and a unidirectional bezel, but Fratello says they are not ISO-certified divers. The 100 m rating should not be presented as proof of formal dive-watch certification. Describe them as sports-style or dive-inspired watches, rather than certified dive instruments.

Which reference should you compare?
Start with the colorway that suits your preference, then compare the published dimensions with watches you already find comfortable. Diameter alone does not determine wrist fit: the reported 44.2 mm lug-to-lug length and 12.1 mm thickness also matter. The sources do not provide comparative wrist tests, so they cannot establish which reference wears smallest or best.
Current prices, stock and regional availability are not established by the launch coverage. Check a current listing for the exact reference and your market before relying on a price or availability claim.
