Search "PINDU P1670" and you'll find almost nothing useful — no full spec sheet, no honest verdict, nothing that confirms the water resistance. That's the gap this review closes. The PINDU P1670 Honeycomb Dial NH35A Automatic is PINDU's $279.99 daily watch: a 40mm stainless steel case, sapphire crystal, a screw-down crown, and a 10 ATM / 100-metre water-resistance rating. Below is every real spec from PINDU's own listing, an honest worth-it call, and the two cheaper PINDU automatics worth cross-shopping before you buy.
Verdict: buy the PINDU P1670 for sapphire crystal plus a 10 ATM / 100-metre case — specs that justify the $279.99 price if you actually want to swim in your watch. Skip it only if you want a smaller case or plan to swap straps often.
The watch this review covers: PINDU P1670, $279.99 — NH35A automatic, 40mm x 12mm, sapphire crystal, jubilee bracelet, 10 ATM/100m.
Cheaper alternative, same movement family: PINDU P6519, $109.99 — NH35A automatic, bolder dial, 3 Bar/30m daily-wear rating only.
Skip it if you want a sub-40mm case or need a quick strap swap — read the lug-width section before you buy.
PINDU P1670 Verdict First: Who Is It For?
The PINDU P1670 suits someone who wants one automatic watch that works for the office, the pool, and everything between, for $279.99. It's built for a buyer who values sapphire crystal and a 100-metre rating over a dramatic dial — the honeycomb texture adds detail without the louder, sportier look of the P6519.
Is the PINDU P1670 Worth $279.99?
Yes, if you want a genuinely swim-rated automatic: the P1670 pairs a 10 ATM / 100-metre case with real sapphire crystal and a Japanese NH35A self-winding movement, all in a 40mm x 12mm 316L stainless steel case. At $279.99 it's PINDU's most practical daily piece — skip it only if you want a smaller case or an easy strap swap.
What you're actually paying for is the combination, not any single spec. Plenty of watches in this price bracket have sapphire crystal or a 100-metre rating. Fewer have both plus a screw-down crown and a jubilee bracelet with a folding clasp. If you want the broader picture of where PINDU sits against other sub-$300 automatics, our roundup of automatic watches under $300 covers more ground, and our honest PINDU brand review covers the brand as a whole rather than one model.
What Movement Is Inside the PINDU P1670?
The P1670 runs on the NH35A, a Japanese self-winding automatic calibre that PINDU also lists in the P6519. It winds itself from wrist motion and needs no battery. PINDU doesn't publish jewel count or power reserve for this specific listing, so treat movement-spec claims beyond what's stated here as general NH35A knowledge, not P1670-specific data.
The practical upside of the NH35A isn't a number on a spec sheet — it's serviceability. The NH35 family is widely used in affordable automatics, which generally makes servicing easier to arrange than with an obscure calibre. For how the movement is built and what its general specs mean, see our full NH35 movement explainer.
Can You Swim With the PINDU P1670?
Yes — PINDU rates the P1670 at 10 ATM / 100 metres, a rating generally treated as suitable for swimming, not just splashes. PINDU doesn't list the P1670 as a dive watch, so treat 100 metres as a swim rating rather than a scuba rating, and make sure the screw-down crown is fully closed before it goes in the water.
That rating is also where the P1670 separates itself from PINDU's cheaper daily automatics. The P6519 Water Ghost, for comparison, is listed at 3 Bar / 30 metres for daily wear — a splash-level rating, not a swim rating. For a plain-language breakdown of ATM ratings generally, read what water resistance actually means on a watch before you rely on any number.
Does the PINDU P1670 Have Sapphire Crystal, a Cyclops Date, and a Fluted Bezel?
Yes to all three. PINDU lists the P1670 with a sapphire crystal that carries an anti-reflective coating, a screw-down crown with a cyclops lens over the date window, and a fluted polished stainless steel bezel. Sapphire resists scratches far better than mineral glass, the anti-reflective coating cuts glare, and the cyclops magnifies the date for faster reading at a glance.
The screw-down crown matters alongside the sapphire — it's part of why the case can carry a 100-metre rating in the first place, since it seals the crown tube rather than leaving it as a simple push-pull fit. If you're still deciding whether sapphire is worth paying for over mineral or acrylic on any watch, our crystal comparison breaks down the real differences in scratch resistance and clarity.
The honeycomb texture itself is paired with applied indices and a luminous coating described by PINDU as fast-charging, so the dial stays readable once the lights go off, not just under a desk lamp.
How Does the PINDU P1670's 40mm Case Wear?
At 40mm across and 12mm thick, the P1670 sits in a wearable middle ground — large enough to read at a glance, slim enough to sit under a cuff. PINDU doesn't publish lug-to-lug length. If you normally wear watches under 38mm, try it on first; if you already wear 40–42mm pieces, it will feel familiar on the wrist.
Twelve millimetres of thickness is also worth noting against PINDU's other automatics: the PINDU P6519 shares the same 40mm diameter but runs 13.5mm thick, so the P1670 sits noticeably flatter on the wrist despite the matching width.
What's the PINDU P1670's Lug Width — and Can You Fit a Leather Strap?
The P1670 ships on a stainless steel jubilee bracelet with a folding clasp, with a lug width PINDU lists as "18 mm taper from 27 mm". The P1670 isn't on the confirmed-fit list for the 22mm quick-release leather strap PINDU sells separately, so measure the gap between the lugs before buying any aftermarket strap — the jubilee bracelet is the better fit for this specific case as-is.
That's a genuine limitation worth knowing before you buy, not after: if changing straps regularly is part of how you plan to wear the watch, the P1670's lug width makes that harder than it is on PINDU models built around the more common 20–22mm sizing.
PINDU P1670 vs P6525 vs P6519: Which Should You Buy?
All three are PINDU automatics priced at $279.99 or less, and each solves a different problem. Here's how they actually compare on paper.
| Model | Movement | Size | Key feature | Price | Who it suits |
|---|---|---|---|---|---|
| PINDU P1670 | NH35A automatic (Japan) | 40mm x 12mm | Sapphire crystal, 10 ATM/100m | $279.99 | Buyers who want a swim-rated daily automatic |
| PINDU P6525 | Japanese automatic self-wind | Not stated by PINDU | Sapphire crystal, numberless dial, steel bracelet | $99.99 | Buyers who want sapphire on a tighter budget |
| PINDU P6519 | NH35A automatic (Japan) | 40mm x 13.5mm | Bolder sport-style dial, mineral glass, 3 Bar/30m | $109.99 | Buyers who want a bolder dial and don't need a swim rating |
Buy the P1670 ($279.99) for sapphire crystal and the only stated 100-metre rating of these three — PINDU doesn't list a water-resistance figure for the P6525. Buy the P6525 ($99.99) for a cheaper sapphire-crystal automatic with a plainer dial. Buy the P6519 ($109.99) for the same NH35A movement in a bolder sport-style case, accepting mineral glass and its 30-metre daily-wear rating.
The PINDU P6525 is the cleanest dress option of the three and sits well in our Dress & Classic collection if business-formal styling matters more to you than water resistance.
Who Should Skip the PINDU P1670?
Skip the P1670 if you want a case smaller than 40mm — that's the only size PINDU lists for this model. Skip it too if you like swapping straps often — the 18mm jubilee taper doesn't match PINDU's 22mm quick-release leather strap, and the P1670 isn't on that strap's confirmed-fit list, so strap-swapping means measuring and sourcing an aftermarket strap rather than using PINDU's own replacement.
If either of those rules it out, the PINDU P6519 uses a 20mm band width with options for either a steel bracelet or a leather strap, which is a more flexible setup if changing straps matters to you — you'd just be trading away the P1670's sapphire crystal and 100-metre rating to get it.
