Short Answer
Buy the tier 1 version of the Lange 2 405.031 with the decorated hand-wound movement and the instant-jump big date. It costs more than the budget copies, but the dial printing, the polished bevels on the lugs, and the date discs hold their own next to the genuine reference in a way the cheap versions do not. If that version is out of stock, the tier 2 automatic is the runner-up. The entry tier works as a first replica, not as a keeper.
Before You Compare
- Measure your wrist and confirm the listed case size with the seller. Copies of this reference show up anywhere between 38 mm and 41 mm.
- Decide whether you want a hand-wound movement you wind each morning or an automatic you can leave in a box on the weekend.
- Check the lug width and strap type, since a 20 mm strap will not fit a 19 mm case.
- Set a budget band and stay in it. The jump between tiers is bigger than the jump in looks.
Our Pick: Tier 1 with Hand-Wound Movement
This is the version to buy. The case carries sharper edges on the lugs, the crown sits flush against the midcase, and the sapphire caseback shows a movement with Geneva stripes, blued screws, and an engraved balance cock. The big date sits in two separate windows with a clean gap and no shadow between the discs. The hands are the correct length, so the minute hand reaches the outer track instead of stopping short.
- Movement: hand-wound, decorated, roughly 42 to 46 hours of reserve
- Date: two-disc instant jump, not a slow creep over several hours
- Case: polished and brushed mix, screw-down caseback ring
- Glass: sapphire front and back, no haze at the edges
- Weak point: strap leather is stiff for the first two weeks
Runner-Up: Tier 2 Automatic
The tier 2 copy uses a modified automatic movement. It runs well and keeps time, but the rotor covers part of the display back and the decoration is stamped rather than striped by hand. The date change is slower, so the window can look half-turned late at night. Dial printing is slightly softer under a loupe. If you wear the watch daily and hate winding it, this trade is reasonable.
Entry Tier: Worth Knowing, Not Worth Chasing
The cheapest copies get the silhouette right and little else. The date discs sit on one plane, so the numerals do not line up. Lume is weak, the bezel polish is uneven, and the crown threads feel gritty. Buy it only if you want the look for a few months.

How to Check a 405.031 Replica Before You Pay
- Ask the seller for a video of the date change at 11:55 p.m.
- Request a close photo of the caseback engraving and the reference stamp.
- Confirm the movement type and the power reserve in writing.
- Check that the hour, minute, and small seconds hands all align at 12.
- Ask about the return window and who pays return shipping.
- Pay with a method that allows a chargeback.
Bottom Line
The tier 1 hand-wound Lange 2 405.031 is the one to order. The date mechanism and the movement finishing are the two places where copies fall apart, and this version handles both. Step down to tier 2 only for an automatic, and treat the entry tier as a costume piece.
