What Replica Lange 3 101.037 Refers To
The number 101.037 belongs to the A. Lange & Sohne Lange 1 reference block. Lange never produced a watch called the Lange 3, so a search for replica Lange 3 101.037 is a search for a copy of a Lange 1. The "3" comes from seller shorthand for third-generation cases and updated dial print, not from the manufacturer.
Reference 101.037 is a manual-wind Lange 1 with the signature off-center layout: a large main dial at 9 o'clock, an outsize date at the top right, a small seconds subdial at the bottom left, and a power reserve indicator at 3 o'clock. Case diameter runs 38.5 mm. Copies of this reference exist in yellow gold, rose gold, white gold, and platinum finishes, with dial colors that range from champagne to black. Confirm the exact metal and dial pairing against the maker's own catalog before you pay, because resale listings reuse this number for more than one variation.
Prerequisites
- A straight-on photo of the genuine reference for side-by-side comparison.
- A phone macro lens or a 10x loupe.
- Case size targets: 38.5 mm wide, roughly 10 mm thick.
- A working budget frame: entry copies under $150, mid grades $200 to $450, high grades $500 and above.
- A return window of at least seven days in writing.
How to Inspect a Replica Lange 3 101.037
- Measure the case across the bezel at 3 and 9 o'clock and confirm it reads 38.5 mm.
- Study the outsize date window and check that the two date discs sit flush with no printed divider between them.
- Compare the seconds subdial position to the genuine photo and note any drift toward the center of the dial.
- Check the power reserve hand and confirm it travels across the full arc when you wind the crown.
- Turn the watch over and look at the caseback glass, then list which finishing details are present: blued screws, gold chatons, a three-quarter plate, and a hand-engraved balance cock.
- Wind the crown slowly and count the turns until the mainspring stops, since a genuine manual Lange 1 takes about 45 turns for a full charge.
- Press the date corrector on the case flank at 10 o'clock and watch the big date jump once per press.
- Weigh the watch on a kitchen scale and compare the figure to the published weight for the same metal.
- Wipe the lug edges with a soft cloth and check for plating rub-through or a color shift against the caseback.
- Inspect the strap stitching and the buckle stamp under the loupe, then ask the seller for a short video of the watch running.
Copy Grades You Will See
Most sellers sort copies into three tiers, and the tier decides which checks above will pass.
- Entry grade: printed dial text, plated base-metal case, quartz or low-grade automatic movement, no power reserve function.
- Mid grade: closer dial layout, working power reserve, decorated automatic movement, gold plating on a steel case.
- High grade: correct 38.5 mm profile, two-disc big date, hand-finished bridge work, and solid gold or gold-capped cases at the top end.
Red Flags
- A big date printed on one disc instead of two.
- A case that measures 40 mm or larger when the listing claims 38.5 mm.
- Photos that hide the caseback or show only stock manufacturer images.
- A seller who refuses a return window or asks for payment outside a traceable method.
What a Copy Cannot Do
A replica Lange 3 101.037 will not carry Lange's movement architecture, its German silver three-quarter plate, or its service history. No copy holds value on the secondary market and no copy can be serviced by the brand. Treat the purchase as costume jewelry with a mechanical heart, buy from a seller who accepts returns, and set your budget at a level you can walk away from without regret.
