Turn every heartbeat into horsepower. The APEX Sport™ fuses Japanese automatic reliability with race-track aesthetics, giving you Swiss-level clarity and dive-hall toughness without the four-figure receipt.
Engineered for wrists that sprint, swim, and succeed:
- Seiko NH35A automatic heart – 24-jewel, 41 h power reserve, hacking & hand-wind; rotor winds from gym reps to red-eye flights.
- 40 mm 316L steel case – brushed top, polished chamfers, 12 mm thick; crown-guards shield the screw-down crown from reef hits and arm-rest knocks.
- Domed sapphire mirror – 2.5 mm box lens, inner AR coating; diamond-hard clarity that magnifies the sun-ray black, navy, or meteorite dial.
- 200 m / 20 ATM water armor – triple-gasket screw-down crown & case-back; swim, surf, shower, snorkel approved.
- 120-click ceramic bezel – 60-minute countdown, lumed pearl; timing laps, lifts, or lunch breaks.
- Swiss Super-LumiNova C3 – green daylight, green night glow on indices & sword hands—legible at 3 a.m. red-eye flights.
- Solid-link Oyster bracelet – screwed pins, micro-adjust clasp, safety-lock; fits 6.3″–8.2″ wrists out of the box and swallows a wetsuit sleeve when adventure calls.
- Motion-powered flex – no battery, no apps—just wrist motion storing 41 hours of reserve for weekend getaways.
Strap it on, set the bezel, and let the APEX Sport track every rep, wave, and deal—individual serial number engraved on every case-back: luxury you can sweat on without sweating the price.

What i really enjoy about this watch is the sense of massiveness it gives. It feels heavy and solid on the wrist in a very satisfying way, making it feel like a serious timepiece. The included strap is comfortable, and it perfectly complements the overall presence of the watch. The open-heart design with the cut-out dial window looks great, letting you peek at the movement, which also shows cleanly through the transparent case back. Watching the mechanism in action gives a strong impression of quality. I also like the 24-hour sub-dial, which corresponds perfectly with the main dial and adds a nice touch of functionality and symmetry. The blue bezel has smooth movement and dial have a striking look, and the overall finishing feels refined for the price point. The lume is decent. In short, the pd-1736 combines heaviness, style, and solid comfort. It feels like a much more expensive watch, and i’m very happy with it.
