New vs Pre-Owned
Selling my extremely sleek 41mm Longines Hydroconquest GMT with black ceramic bezel and sunburst dial on the most comfortable strap out of any watch I've had!

Ref. L3.790.4.56.9

Only a few months old - warranty active till 10.02.2031 

Near mint cosmetic condition:
No noticeable scratches, only the faintest signs of careful use.
Crystal is pristine and unmarked.
Looks and feels absolutely phenomenal on the wrist.

Excellent mechanical condition (timegrapher tested).

Longines L844 GMT automatic movement performing excellently with strong amplitude and very stable positional results.

I'm not a strap guy but I kind of prefer this strap over most bracelets, cetainly over all other straps.
It feels extremely high quality, it's light-weight, wraps around the wrist perfectly and features on-the-go micro-adjustments!

My wrist is 6.5 inch slim and this 41mm case still fits beautifully. It will suit both larger and smaller wrists.


Comes with:
- Outer cardboard box
- Inner presentation box
- Warranty card (Stamped Chrisholm Hunter - 10.02.2026 - Longines warranty till 10.02.2031)
- Purchase invoice
- eBay Authenticity certificate
- Instructions leaflet

Please note that the bracelet on the timegrapher photo is not included, I had it on the steel bracelet at the time.
I will be selling the bracelet separately.

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.

Returns

All watches at Zero Hour Watches are sold as described and as seen. Each piece is carefully inspected, tested for accuracy, and photographed in detail to ensure you know exactly what you’re buying.
