Selling my Longines HydroConquest Ceramic Chronograph 43mm on the black rubber strap.
One of my favourite dive chronographs. I love the monochrome colourway with the small pops of red on the chronograph hands. Very sporty and masculine - a perfect summer chronograph diver with serious wrist presence.
Comes with a valuation certificate for £1,880.
Good cosmetic condition with light signs of wear on the case and lugs.
The main imperfection is a small dent on the lower side of the case around 9 o'clock. It's not particularly noticeable during normal wear but it is there and I have tried to show it clearly in the photos.
The rest of the watch is in fantastic shape.
The AR coated sapphire crystal is pristine and unmarked. Overall it looks fantastic on the wrist.
The rubber strap is in fantastic condition and is currently sized to fit roughly an 8 inch wrist, so there is plenty of room to cut it shorter if required.
Excellent mechanical condition (timegrapher tested across 5 positions):
Approximately +1 to +5 s/day depending on position, with strong 295° to 336° amplitude and excellent 0.0 to 0.3 ms beat error.
The Longines L688 automatic column-wheel chronograph movement is running very strongly overall, with excellent amplitude, very low beat error and outstanding positional consistency with only around 4 s/day variation across the tested positions.
Chronograph functions as expected and resets cleanly with no issues.
Full set including:
- Outer cardboard box - front flap has come away and is secured with tape, fairly common on these older Longines boxes
- Inner presentation box - great condition
- Warranty card dated 22.07.2020
- Valuation certificate
- Instructions booklet
- Longines date changing tool
- Swing tags
Please study the photos as they form part of the description.
I have tried my best to show any imperfections under bright light.
Serial number is censored for security.
Happy to take sensible offers.
Any questions just shoot me a message.
Thanks for looking.

Why buy from Zero Hour?
All the products on this shop are available to buy on eBay and Vinted but at a higher price to accommodate the hefty platform selling fees.
I made this website so I can offer the best deal possible and be able to control the price.
If you prefer to buy the watch on our ebay/vinted stores and don't mind the higher price on there than that's perfectly fine.
Condition
Please review photos carefully - they form part of the description. Watches are pre-owned and may show light signs of wear consistent with age. Timekeeping is measured on a timegrapher, but we do not guarantee accuracy equivalent to a brand new unit purchased from an authorised dealer.
Water Resistance
Unless specifically stated with a recent pressure-test date, water resistance is not guaranteed.
