Short answer
The replica Lange 1 Time Zone 704.035 is a copy of the A. Lange & Söhne Lange 1 Time Zone in the case metal and dial combination that carries that reference number. Four details decide whether a replica looks convincing: the off-center main dial, the outsize date, the city ring that drives the second time zone, and the power reserve indicator. Get those right and the watch reads correctly from across a table.
What the reference number tells you
A. Lange & Söhne assigns a separate reference to each metal and dial pairing inside a model line. The 704.035 designation points to one specific pairing in the Lange 1 Time Zone family, so a watch sold under that number should match that exact combination rather than a generic Lange 1 with an extra dial. When a seller uses several reference numbers to describe one build, the listing is usually vague about which version is being shipped.
Details worth inspecting
- Case profile: the Time Zone case is wider than the classic Lange 1, with a slim bezel and straight lugs. Look at how the case sides catch light and whether the lugs taper with a clean edge.
- Dial layout: main time dial sits high and left, small seconds below it, outsize date at the top right, power reserve arc on the right side. Spacing should stay even all the way around.
- City ring: city names printed small, sharp, and level. Rotate the ring slowly and check for doubled or crooked print.
- Outsize date: both discs should sit flush inside the window and change at the same moment.
- Hands: faceted alpha-style hands with a crisp center crease. Hold the watch under a lamp and check the tips.
Testing the dual time zone
The second zone reads from the city ring, and a pusher on the case side moves the ring in one hour steps. On the original design, when the ring passes the home city the main time jumps by an hour, so the two zones stay in sync. A working replica should do the same: push until the ring reaches the reference city, then check that the main hands advance together with it. If the ring moves while the main time stays put, or if nothing moves at all, the complication is decorative. Look for a small day or night disc on the second zone dial as well. Without it, a 3 a.m. reading in another city looks the same as 3 p.m., which is the easiest tell on a cheap build.
Movement and feel
Most replicas in this size run an Asian automatic or a Swiss-style automatic, sometimes with a hand-wound option. The case back usually shows decoration such as Geneva stripes, circular graining, and engraved lettering. Judge the movement by function rather than by looks: winding should feel smooth, the crown should set both zones without grinding, and the watch should run a full day on a wind. Expect a reasonable weight. The original sits just under 42 mm across, and replicas usually follow that footprint, though a light case on a large watch is a common giveaway.
Points to keep in mind
Counterfeit watches are illegal to sell in the United States and in many other countries, and a replica is not an A. Lange & Söhne product. Treat one as a fashion piece, not an investment, and check the rules where you live before buying or reselling. A replica also will not hold value the way a genuine watch does, and service options are limited to the seller or a general watchmaker.
FAQ
Does the replica have a real second time zone?
Better versions do. The city ring and the pusher should change the second zone, and the main time should follow when the ring crosses the home city.
What should I check first?
Start with the city ring and the outsize date. They sit at the center of the dial and any misprint or misalignment shows up right away.
Is the sizing close to the original?
Most listings follow the original footprint of just under 42 mm, with a case height that suits a dress watch. Ask for exact measurements before ordering, since a few millimeters changes how it wears on a smaller wrist.
