The Phylida 500m Automatic Diver is built for buyers who value engineering over branding.
With a no-date NH38A automatic movement, 50-bar water resistance, and a ceramic dive bezel, this watch prioritizes clarity, durability, and functional design—without unnecessary complications.
This is a true tool watch: legible, overbuilt, and mechanically honest.

500 meters / 50 bar water resistance – serious dive capability

NH38A automatic movement – no-date, cleaner dial, proven reliability

Case & Wearability
At 43.5mm, the case offers strong wrist presence without becoming unwieldy.
The 50mm lug-to-lug keeps it stable on the wrist, while the 20mm lug width allows easy strap swaps if you prefer rubber or NATO alternatives.
Despite its 16mm thickness, the case is well-balanced and purpose-driven—appropriate for a 500m diver.
Movement: Seiko NH38A (No-Date)
The NH38A automatic movement is a no-date variant of the trusted NH series.
Why it matters:
-
Fewer moving parts
-
No phantom date position
-
Cleaner dial symmetry
-
Easy servicing and long-term reliability
This movement choice aligns with tool-watch fundamentals.

FAQ
Is the Phylida 500m suitable for professional diving?
Yes. With 50-bar water resistance, screw-down crown, and ceramic bezel, it meets the expectations of a serious dive watch.
Why choose the NH38A over NH35?
The NH38A removes the date complication, resulting in a cleaner dial, fewer moving parts, and no unused crown position.
Is the crystal real sapphire?
Yes. The watch uses domed sapphire crystal, offering superior scratch resistance compared to mineral glass.
How does it wear on the wrist?
Despite its thickness, the 50mm lug-to-lug and solid bracelet keep the watch balanced and secure on medium to large wrists.
Can I swap the bracelet for a strap?
Yes. The 20mm lug width supports NATO, rubber, and leather straps.
