New vs Pre-Owned
Selling my extremely sleek 41mm Longines Hydroconquest GMT with brown ceramic bezel and 'sunray brown' dial on an extendable bracelet..

I think this brown variant is one of the best looking one out of the whole new generation hydroconquest - there's just something about the gold indices, cream lume, combined with everything else into a somewhat vintage aesthetic but at the same time unmistakably modern.

Ref. L3.790.4.66.6

Warranty active till 04.04.2030 

Excellent cosmetic condition:
Only light signs of casual wear on the case and bracelet noticeable upon close inspection.
Crystal is pristine and unmarked.
Overall fantastic and looks absolutely phenomenal on the wrist.

Excellent mechanical condition (timegrapher tested):

0 to +2 s/day average, ~244–294° amplitude, 0.3–0.7 ms beat error @ 25,200 vph (tested at 51° lift angle)

Longines Calibre L844 GMT automatic movement running very strongly, with COSC-level accuracy, excellent positional stability, healthy amplitude, and clean overall timegrapher results.


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

The strap is extremely comfortable and features a very well engineered clasp with on the go micro-adjustments. This is the biggest upgrade over the previous generation Hydroconquests in my opinion.


Comes with:
- Outer cardboard box
- Inner wooden presentation box
- Warranty card (Stamped Robert Gatward Jewellers 04/04/2025 - Longines warranty till 04/04/2030)
- Original purchase receipt
- Instructions booklet
- 4x spare links (currently sized to fit 6.5-inch wrist)

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.
