The Ratio RTF covers the sport automatic brief in the Ratio catalogue — bold case design, automatic movement, 100m water resistance and sapphire crystal at prices that position it as the sport-first companion to the Freediver’s dive credentials. Where the Freediver line is built around water depth ratings and dive tool specifications, the RTF is designed for active everyday wear across outdoor, casual and sport contexts without the dive watch bulk.
RTF Design and Build
The RTF carries an automatic movement — the reliable NH35 Japanese calibre at 21,600 vph with 41-hour power reserve, hacking and hand-winding — in a 316L stainless steel case with sapphire crystal. The case design leans toward the sport end of the aesthetic range with bolder proportions and more aggressive finishing combinations than the Ratio GMT or Quest. Water resistance is 100m with a screw-down crown, covering swimming and daily active use without the extreme case engineering of the Freediver depth-rated line.
The dial design across RTF variants covers darker colour options and more detailed sector layouts than the cleaner minimal approach of the Quest and GMT. These are watches designed to make an impression on the wrist rather than disappear under a shirt cuff.
RTF vs Other Ratio Automatics
Within the Ratio automatic range, the RTF sits beside the Ratio Street Racer in sport-first design intent rather than the tool watch focus of the Freediver or the travel watch function of the Ratio GMT. The honest distinction is aesthetic rather than specification — all Ratio automatics share the NH35 movement and sapphire crystal standard. The RTF is the choice for buyers who want the most visually assertive case design in the Ratio catalogue.
Who the RTF Is For
The RTF suits buyers who want automatic movement character in a sport case design for everyday active wear. It is not a dive watch — 100m water resistance covers swimming but not dive use. It is not a dress watch — the case proportions and design are too assertive for formal contexts. It sits comfortably in the sport casual and outdoor activity bracket, worn daily for the mechanical movement satisfaction without the specific tool watch function of the Freediver.

Frequently Asked Questions
What movement does the Ratio RTF use?
The Ratio RTF uses the Seiko NH35 automatic movement at 21,600 vph with 41-hour power reserve. The same calibre powers the Ratio Freediver range. It hacks and hand-winds.
Is the Ratio RTF a dive watch?
No. The Ratio RTF carries 100m water resistance — suitable for swimming and daily active wear but not for pressurised dive use. The Ratio Freediver 200m, 500m and 1000m cover the dive watch category within the Ratio range.
Does the Ratio RTF have sapphire crystal?
Yes. The Ratio RTF uses sapphire crystal as standard across the range.
How does the Ratio RTF compare to the Ratio Freediver?
The RTF shares the NH35 movement and sapphire crystal with the Freediver but carries 100m rather than 200m to 1000m water resistance and a sport aesthetic rather than dive tool design. The RTF is smaller and lighter than the Freediver depth-rated models.
What size is the Ratio RTF?
Check the specific variant’s product listing for exact case diameter and lug-to-lug — these vary across RTF configurations. The range generally runs between 40mm and 44mm in case diameter.
