Top pick
The pick is the 36 mm version with a stamped guilloché dial, sapphire front and back, and a hand-wound movement with a power-reserve hand that moves when you wind the crown. Price sits near $260 to $340. Two details decide it: the dial pattern is cut into the metal, not printed on top, and the reserve hand tracks the mainspring instead of sitting at a fixed point.
Skip any listing where the seller shows one photo only, or where the caseback text is blurry. Those are the two signs of a stock-photo listing.
What the Breguet 3890 is
Reference 3890 sits in the Breguet Classique line. Round case, coin-edge caseband, straight lugs, engine-turned dial, blued steel Breguet hands with open tips. The genuine watch uses an 18k gold case and a hand-wound movement. Catalogs list the case at about 36 mm; confirm the size for the exact variant, since Breguet made several 3890 sub-references in yellow, white, and rose gold.
Replica makers copy the outside. The movement inside is a generic hand-wound calibre, and the gold is gold plating over brass or steel.
Checklist before you order
- Case diameter and lug width. Ask for a caliper photo.
- Dial depth. Stamped guilloché casts a shadow under light. Printed pattern looks flat.
- Hands. Blued steel reads dark blue with a slight sheen; painted hands read flat navy.
- Power reserve. Ask for a short video of the winding and the hand moving.
- Crystal. Sapphire on both sides at this price. Mineral glass scratches in weeks.
- Caseback engraving. Serial placement, font weight, depth of the stamping.
Options by tier
Under $200
Printed dial, mineral glass, no working power reserve. The case profile is close. The dial is the weak point.
$200 to $350
Stamped dial, sapphire, working reserve hand, plated case. This is the range where the 3890 copy looks correct at arm's length and holds up in photos.
Above $350
Better case finishing and closer dial text. Check what changed. Some sellers charge more for the same watch with a different strap.
What no replica gets right
Gold content, movement finish, and the depth of the hand engraving on the caseback. Judge the copy on dial, case shape, and hands. A replica is a copy, not a Breguet, and it carries no factory service.
