£2,000 and up

Dampened Seiko perfection in a beautiful case, let down by a micro-adjust clasp that marks its own links.

One of the best Seikos ever made. Gethin would pick it over the HBF1.

His favourite watch ever: a mesmerising Zaratsu case and Hi-Beat sweep, Seiko magic incarnate, but it scratches if you look at it and has no bracelet.

A dial that won him over: splendid cave-diver gradient on the proven SLA case and bracelet, though the clasp is the usual letdown.

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.

High-quality, comfortable, 'wears like an SKX', but he doesn't think it's for him, and the stamped clasp is a sore point at this price.

The black one of the pair, which he slightly prefers: high-quality, comfortable, 'wears like an SKX', but not for him, and the stamped clasp is a sore point.

Seiko's pinnacle in Gethin's eyes: flawless titanium finishing, a sublime bezel and a fantastic bracelet, all of it unreal.

The faithful original: top finishing and the best bezel feel of the pair, but the X on the dial and the metal strap keeper annoy him.

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 sublime, glamorous reinterpretation of the Willard: papery charcoal dial, silky ceramic bezel and the same top-tier finishing as the SLA033 for much less.

His favourite watch case ever on a British-racing-green dial, with buttery bezel action, his favourite handset and mental lume. He can't choose between it and his SLA023, and only the painted triangle worries him.

His grail and favourite Marinemaster: an unmatched Zaratsu case, the best bezel action and handset he's ever known and Christmas-tree lume. The Prospex X, the painted triangle and the unregulated movement are the only things stopping it being perfect.
