Under 40 mm case

An excellent, wearable white-dial field GMT that made him 'feel like a king'; only quibbles are a busy dial, weak lume and a thick glass back.

His pick as the best Seiko 5 currently available: tiny, light, beautifully finished, with a standout black dial and a bracelet well above Seiko 5 norms.

A remarkable-looking, very comfortable and beautifully finished three-hander that Gethin would seriously consider buying, despite disliking the Alpinist.

A well-made, slim and comfortable skin-diver case that Gethin likes but does not love: overpriced at GBP 2,930, with a weak clasp and end-link integration.

The best Seiko he has ever worn: a glimmering anthracite sunburst dial, a Zaratsu skin-diver case and insane comfort, let down by a rubbish bracelet and a limited-edition premium.

A small-batch New Zealand field watch, excellently executed, that Gethin loved enough to pay over retail for.

A staggeringly beautiful £236 Seiko with one of the brand's best cases; the factory bracelet lets it down.

An entry-level in-house automatic for under £70 with an exemplary military dial. 'I think it's great.'

A 29.5 mm, 300-metre ladies' Conquest he'd wear himself if it were bigger; the polished case scratches easily.

A tungsten-carbide, Powermatic 80 day-date he calls 'a great first automatic for anyone's girlfriend or wife'.
