Some watches whisper quality the moment they catch the light — the PX1721 is one of them. The star of the show is its Aventurine gemstone dial, a genuine mineral face flecked with tiny reflective crystals that shimmer and shift with every turn of the wrist, giving it a depth no printed or sunburst dial can match. Circling it is a fully-lumed sapphire bezel insert — not just a single glowing pip, but the entire ring charged with BGW9 luminova, so the whole bezel glows evenly in the dark. Hands and markers are lumed the same way, making this as capable after sunset as it looks during the day.
Built on a genuine PT5000 automatic movement, the case is 316L stainless steel at a wearable 39mm, finished with a sapphire crystal carrying anti-reflective coating on both sides for a clear, glare-free view of that dial. A screw-down crown and screw-down case back (stamped with Proxima's signature Manta Ray logo) help deliver a true 20 Bar/200m water resistance rating — genuinely dive-capable, not just a number on a spec sheet. The 316L steel bracelet uses a tapered design with quick-release links for easy sizing and strap swaps.
This is a watch that rewards a closer look — the kind of piece that photographs well and wears even better.
