New vs Pre-Owned
Here we have one of my all time favourite watches 
and probably one of the most badass Swiss divers:

Blue Longines HydroConquest Automatic 41mm with the aluminium bezel.
Ref. L3.642.4.96.6

Good cosmetic condition:
The watch has been worn and loved. Looking close, small dents and scratches on the case, bezel and bracelet can be observed. Overall nothing obtrusive and normal for the age and looking amazing on the wrist. Has had a light polish and looks fantastic.
No scratches on the glass.

Perfect everyday beater watch if you ask me!


Excellent mechanical condition and timekeeping (timegrapher tested):
+5 to +8 s/day average, 240–274° amplitude, 0.0–0.2 ms beat error @ 28,800 vph
Longines cal. 633.5 automatic movement performing very well, running comfortably within expected tolerances with healthy amplitude, good positional stability, and clean beat alignment.

Overall the watch is stunning, with this bluesunburst dial and
the 41mm case providing solid masculine presence 
that suits both large and small wrists - one of my favourite divers.

The lugs are nicely rounded so it fits greatly on smaller wrists like 
mine (6.5inch photographed). 

Bracelet features a diving extension for a quick 
resize to fit over a wet suit.
One of the sides of the bracelet connects to the clasp with a half link rather than end link - doesn't affect performance or wearability and is very difficult to notice.
These can be sourced online if needed.

Comes with: 
- Outer box,
- Inner box, 
- Booklet,
- Generic rubber strap

No spare links - currently sized to comfortably fit a 7.5 inch wrist

Current model for £1,300

Please study the photos as they form part of the description, 
I have tried my best to show any imperfections under bright light.

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.
