Buy the 39mm. For a wrist that measures about 6.3 to 7.5 inches (16 to 19 cm) around, the fake Portofino 39 sits the way a Portofino should: thin, flat, dressy, and clear of the wrist edges. Under 6.3 inches, take the 37mm. Over 7.5 inches, look at the 40mm automatic or the 42mm chronograph. The 39 is the middle that almost nobody sends back.

How the 39mm case wears
A Portofino is a dress watch, so the number on the listing tells you less than you think. The 39mm case usually measures about 46 to 47mm from lug tip to lug tip and roughly 9mm thick. The bezel is thin and the dial is open, which makes the watch read larger on the wrist than a 39mm sports watch with a fat bezel. The strap is 20mm at the lugs and tapers to 18mm at the buckle, and that taper is a big part of why it looks slim.

One warning: replica listings round numbers. I have seen "39mm" cases measure 38.4mm on calipers and "40mm" cases measure 39.2mm. Treat the label as a starting point, not gospel.

Measure two things first
- Wrist circumference. A strip of paper and a ruler is enough. Measure just behind the wrist bone.
- Flat top width. Look at the top of your wrist and measure the flat area between the two side bones. This is the real limit. If the lug tips hang past that flat area, the watch looks borrowed.
Wrist size to case size
- Under 6.0 in (15 cm): 37mm. The 39 will overhang and the lugs will dig in.
- 6.0 to 6.3 in (15 to 16 cm): 37mm if you want a classic fit, 39mm if you like some presence and wear it loose.
- 6.3 to 7.5 in (16 to 19 cm): 39mm. This is the sweet spot, and it covers most men and plenty of women.
- 7.5 to 7.9 in (19 to 20 cm): 39mm still works, but the 40mm automatic fills the wrist better.
- Over 8 in (20 cm): 40mm automatic or the 42mm chronograph. The 39 will look small, which is fine if that is the look you want.
If you are stuck between two sizes
Use the lug-to-lug rule. Put the case length against your flat top width. If the lugs stay inside that flat area, buy the larger size. If they spill over, drop down. Diameter gets all the attention, but case length and thickness are what decide whether a dress watch looks elegant or clumsy on your arm.

What to check on the replica itself
Size is only half the purchase. Before you pay, confirm the case diameter with a photo on calipers, the thickness (9 to 9.5mm is right for this style), the 20mm lug width, and the crown position at 3 o'clock. Ask about the movement, since a thin case usually means a clone of a Miyota 9015 or an A2892, and each has its own service story. Check that the date window sits where it should and that the dial printing is thin and sharp, because a thick font is the fastest way to spot a cheap Portofino at arm's length. Finally, look at the strap. Stock straps on these are often stiff and plasticky, and a soft 20mm leather strap in the right color changes how the whole watch reads.
Strap and fit notes
Because the case is thin, strap thickness matters more than on a diver. A 2.5mm padded strap will make the watch sit tall on a small wrist. A flat 2mm strap keeps the low profile. If you are between sizes, remember you can always add a hole, but you cannot make a too-long case shorter.
