A BRIEF HISTORY OF TIME(KEEPING): LANCO (LANGENDORF)
Langendorf Watch Company was a Swiss watchmaker known for its fine craftsmanship and great attention to detail. Around 1890, it was probably the largest producer of watches in the world.  In 1965 it was bought by Omega / Tissot and a short time later relaunched with a more funky 70s vibe, watches being produced in the Omega factory.  The commercial success of Omega at the time meant they acquired many companies who were struggling with the quartz influx but Lanco was one of the very few to retain its identity and still have watches produced under that name, despite being made by Omega.

ALL YOU NEED TO KNOW ABOUT MY WATCHES
We have been avid watch collectors for many many years.  We never wasted our time on modern trends, instead collecting vintage pieces with more class, history and workmanship.  These days people go for the name, even though the watch is probably churned out in a factory and actually worth not much more than a Timex.
In these uncertain times the right watches are one of the most sensible investments you can make.  Quality vintage watches increase in value year on year - whereas many other investments have proven to be decidedly unpredictable.
Every single watch is tested as follows before dispatch:
Manual watches - bench tested for time-keeping and tolerance for 24 hours and left to fully unwind before posting.
Quartz watches - capacitance tested and fitted with a new silver oxide battery and posted with active hack, if applicable.
We have a dedicated room for all of our watches to be stored in, fully temperature and humidity controlled.
Wrist watches will be sent with the strap they have on.  Even if a strap is "ropey" I will not change it as it may be original and to swap for a new strap will devalue the watch.  Feel free to fit a new strap (they are consumable anyways) but I advise to keep the original as collectors will always look for this.
Watches are appraised periodically in bulk - appraisals are not available individually without paying the sole item appraisal fee.  If you wish to obtain this then please contact me and I will advise on the cost.  This fee MUST be paid in full, in advance.  The appraisal value will be included in the description above where appropriate.
Etsy have a limit on the price of items (max £42,000 I think) so the cream of the collection cannot be listed here unfortunately.

SHOP POLICIES:
1. Legalities - all sales are conducted under the terms of the Consumer Contracts Regulations 2013, the Consumer Rights Act 2015 and the Distance Selling Regulations 2000.  Where site policies fall outside these ACTS OF LAW (and believe me they do) the law has full precedence.
2. Returns - all items can be returned within 14 days of receipt if not happy, at buyer's expense.  Original postage will not be refunded unless there is a proven error in the listing but we do not charge a restocking fee.
All items must be returned in original packaging, as per CCR 2013.
3. Postage - all items are posted as soon as we are able and all tracking and insurance info is provided, if applicable.
4. Reviews - We want you to be happy.  If there is a problem of any kind please contact us in the first instance and we will do all we can to resolve.
5. Dimensions - All measurements and details are given as accurately as possible but should be considered as a guide only.  Small discrepancies may occur when using different measuring tools.
PLEASE ASK ALL QUESTIONS BEFORE MAKING YOUR PURCHASE.
