Longines Master Collection Moonphase Chronograph 40mm | L2.673.4.78.3

I don't know many other watches at this price point that offer this many complications in such an elegant package as Longines do with this stunning 40mm Master Collection.

In a way, it's an entry into the world of high horology. Once you've added something like this to your collection, you've probably reached the point of no return. You're now deep into watch collecting and the rabbit hole only gets deeper!

The beautifully detailed silver dial, moonphase complication, full calendar and column-wheel chronograph make this a seriously impressive piece of watchmaking.

I never thought I'd be able to pull off a watch like this with my slim 6.5-inch wrists, but the 40mm case and relatively short lugs actually fit beautifully. Looks and feels absolutely phenomenal on the wrist.

I'll upload a detailed review of this beauty on the Zero Hour Watches YouTube channel – stay tuned.

RRP: £3,350

Excellent cosmetic condition:
Just the lightest signs of casual wear on the case and leather strap, visible only upon very close inspection. Both the front sapphire crystal and exhibition caseback crystal are pristine and unmarked.

Overall, a beautifully preserved example that looks fantastic on the wrist.

Excellent mechanical condition (timegrapher tested across 5 positions):
Approximately -1 to +2 sec/day depending on position, with healthy 252° to 281° amplitude and excellent 0.0 to 0.3 ms beat error at 28,800 vph.

The Longines L687.2 automatic column-wheel chronograph movement is running exceptionally well, showing excellent amplitude, extremely low beat error and outstanding positional consistency across all five tested positions.

• Original Longines wooden presentation box
