PINDU's catalog splits into two very different size stories: a run of 40mm automatics most shoppers never find, and a run of statement pieces between 45.5mm and 48mm that read big on any wrist. Diameter alone won't tell you how a PINDU wears — thickness does more of the work, and nobody selling these watches publishes both numbers side by side. This guide sorts all eight in-stock PINDU models here by diameter, thickness and strap width, so you can match one to your wrist before you buy, not after.
Quick picks by wrist size:
- Small wrist, slim fixed 40mm case: PINDU PD6618 — $269.99, 40mm, 12mm thick, Miyota 8215 automatic, 22mm leather strap.
- Small-to-medium wrist, lowest price: PINDU PD6510 — $107.99, 40mm, about 13.5mm thick, sapphire crystal, 100m rated.
- Medium wrist, dress-sport: PINDU P6589 — $199.99, 40mm two-tone automatic chronograph.
- Large wrist, boldest case: PINDU PD6666 — $347.99, 45.5mm dial diameter, 22.5mm thick.
- Large wrist, biggest diameter: PINDU P6676 — $299.99, 48mm, 15mm thick.
Skip it if: skip the PD6666 (22.5mm thick) and M2791B (20mm thick) if you wear fitted shirt cuffs; skip the PD6618 if you want sapphire or more than 30m water resistance — it has mineral glass and a 3ATM/30M rating, while the PD6510 has sapphire crystal and a 100m rating for $107.99; skip the P6589 if thickness is your deciding number, because its listing doesn't give one. None of the eight listings publish a lug-to-lug measurement, so diameter and thickness are the best numbers you'll get before buying.
How big are PINDU watches?
PINDU's range splits into two clusters: four 40mm automatics (P6589, PD6510, PD6618, PD6515, plus the PD6502 at its 40mm low end) and three statement pieces between 45.5mm and 48mm (PD6666, M2791B, P6676). Thickness varies far more than diameter, from 11mm to 22.5mm, so check both numbers before you buy.
All eight models in this guide are automatics — no quartz movements on this list. That matters for sizing too: even the 40mm models with a listed thickness here run 11mm to 13.5mm, so check thickness as closely as diameter. (The P6589's listing doesn't state a thickness.)

Two listings — the P6589 and the PD6510 — don't state a strap width, so measure your existing strap before ordering a replacement for either. For general lug-width terminology and how to measure it yourself, see our strap and lug width guide.
Which PINDU watches are 40mm?
Four of the eight PINDU models here measure 40mm across: the P6589 chronograph, the PD6510 GMT, the PD6618 skeleton, and the PD6515 square-case automatic. The PD6502, an open-heart skeleton automatic, starts at 40mm too, though its listing gives a 40–44mm case range rather than a single size, so plan for anything up to 44mm.
These five are the answer to "does PINDU make a 40mm watch" — a question that returns nothing useful if you search for it. What separates them is thickness and case shape rather than diameter: the PD6618 (12mm) and PD6502 (11–12mm) sit flattest on the wrist, the square-cased PD6515 sits at 13mm, and the PD6510 is the thickest of those with a listed thickness at about 13.5mm (the P6589's listing gives no thickness), in a case that pairs a rotating bezel with sapphire crystal and 100m water resistance.
PINDU PD6618, $269.99 — 40mm diameter, 12mm thick, on a 22mm leather strap.
Is a 46mm PINDU too big for your wrist?
On a large wrist (over about 18.5cm), usually not. On a small wrist (under about 16.5cm), often yes, especially once the case passes 20mm thick. PINDU's 45.5–48mm pieces range from 15mm thick (P6676) to 22.5mm (PD6666), and that thickness, more than the diameter, decides how big they wear.
The clearest example of why diameter alone misleads: the PD6666 and M2791B are both listed at 45.5mm (the PD6666 as its dial diameter, the M2791B as its case diameter), yet the PD6666 is 22.5mm thick against the M2791B's 20mm — a 2.5mm difference you'll feel at the cuff. The same pattern shows up elsewhere in PINDU's wider range. Two other in-stock models, the PINDU PD6652 and the PINDU PD6631, both run the 46mm diameter people search for directly, yet the PD6652, a Horse Gambling Series racing-roulette-themed automatic ($379.99), is 16mm thick while the PD6631 Panda Series ($299.99) is 20mm. So PINDU's 46mm roulette watch is 16mm thick — 6.5mm slimmer than the PD6666. If you're weighing "is 46mm too big," thickness is the question that actually answers it, not the diameter number by itself. None of these listings state a lug-to-lug length, so treat diameter plus thickness as the fullest picture available before you order.
PINDU PD6666, $347.99 — 45.5mm dial diameter, 22.5mm thick, 22mm silicone strap.
Why does case thickness matter more than diameter?
Because thickness decides whether a watch sits flush on your wrist or lifts off it. Among the eight models here, thickness runs from 11mm (PD6502) to 22.5mm (PD6666) — a gap far bigger than the 8mm spread in diameter. A thin 40mm case can wear smaller than a thick 45.5mm one.
A thicker case isn't automatically a flaw — it's usually there for a reason. The PD6666's 22.5mm case houses a dual flying-wheel skeleton dial that puts the movement on show. It is built as a statement case, not a dress watch. The M2791B's 20mm case carries a skeletonized dial and an oversized design built for presence on the wrist, not for slipping under a cuff. Compare that to the PD6502's 11–12mm case, which still fits an open-heart skeleton design into the slimmest case in this guide.
Which PINDU fits under a shirt cuff?
The PD6502 (11–12mm) and PD6618 (12mm) are the thinnest cases here and the easiest to slide under a dress shirt cuff. The PD6515 (13mm) and PD6510 (13.5mm) come close. The PD6666 (22.5mm) and M2791B (20mm) are built as wrist statements, not cuff watches.
If cuff clearance matters more than anything else, start with the PD6502 or the PD6618 — both are listed at 12mm or less, the slimmest cases in this guide. Some PD6502 colourways carry a stone-set bezel, as in the photo below, so if you want the simplest cuff profile choose a plain-bezel version. We've gone deeper on the PD6502's full spec sheet in our PD6502 review if you want more detail before deciding.
PINDU PD6502, $157.99 — 40–44mm diameter, 11–12mm thick.
Which PINDU watch suits your wrist size — small, medium, or large?
For a small wrist, the PD6618 and PD6515 (both fixed 40mm cases, 12–13mm thick) are the safest fits, with the slim PD6502 (11–12mm thick, but listed at 40–44mm) close behind. A medium wrist can comfortably wear the PD6510 or the P6589's two-tone chronograph. A large wrist suits the bigger statement pieces — the PD6666, M2791B, or the 48mm P6676.
Wrap a soft tape (or a strip of paper you then lay against a ruler) around your wrist just above the wrist bone. As a general rule of thumb, under about 16.5cm (6.5in) is a small wrist, 16.5–18.5cm (6.5–7.25in) is medium, and over 18.5cm (7.25in) is large. Our watch size fit guide explains the reasoning. Then map your number to a PINDU here:
- Small wrist: PINDU PD6502 (40–44mm/11–12mm), PINDU PD6618 (40mm/12mm), PINDU PD6515 (40mm/13mm). The PD6618 and PD6515 are fixed 40mm cases; the PD6502's listing gives a 40–44mm range, so on a very small wrist start with one of the other two.
- Medium wrist: PINDU PD6510 (40mm/13.5mm) for a clean everyday case, or PINDU P6589 (40mm) — its three-register dial and gold-tone tachymeter bezel give it more visual presence than its diameter alone suggests.
- Large wrist: PINDU PD6666 (45.5mm/22.5mm), PINDU M2791B (45.5mm/20mm), or PINDU P6676 (48mm/15mm) for the biggest diameter on the list.
PINDU M2791B, $289.99 — 45.5mm diameter, 20mm thick, 20–24mm leather strap.
What strap width do PINDU watches use, and can you swap straps?
Strap widths across the eight models run from 20mm to 24mm, whether fixed — 20mm on the PD6515, 22mm on the PD6618 and PD6666 — or given as a 20–24mm range on the PD6502, P6676 and M2791B. Two listings (P6589, PD6510) don't state a width at all.
That 20–24mm band covers most standard men's straps, which is why swapping one is usually just a spring-bar job rather than a trip to a watchmaker. Two in-stock replacements are worth knowing: the PINDU Classic Leather Watch Strap ($22.99, black or brown; listed as a one-size strap for standard PINDU watches, with no width stated) and the PINDU Stainless Steel Milanese Mesh Bracelet ($24.99, 22mm) — its width matches the 22mm band width listed for the PD6618 and PD6666, but check the confirmed-fit model list on its product page before ordering. Before buying a replacement for the P6589 or PD6510, measure the strap you already have, since neither listing states its width. Browse the full range in our watch straps collection.
PINDU P6676, $299.99 — 48mm diameter, 15mm thick, 20–24mm tapered silicone strap.
Which PINDU should you actually buy?
For most wrists and anyone who wears a dress shirt, buy the PD6618 ($269.99, 40mm, 12mm thick), or the PD6510 ($107.99, 40mm, about 13.5mm) if price matters most. If your wrist is over about 18.5cm and you want presence, the P6676 ($299.99) gives the biggest case on the list (48mm) at a moderate 15mm thick. Choose the PD6666 ($347.99, 22.5mm) only if you want the boldest case and rarely wear tight cuffs. Match your pick against the table above, check the strap width against what you'd want to swap in later, and buy from the eight here since every one is in stock with worldwide shipping and buyer protection.
