40 to 42 mm case

A rad, comfortable little PADI Samurai with a superb green dial that Gethin loves, held back by a so-so stamped clasp; great at 400-450 pounds.

Smart, well-built and in a gorgeous cobalt, but the octagonal bezel isn't for him: he'd wear it to the office, not the beach.

A love-it-or-hate-it 1980s brute and Gethin's favourite: best bezel of his Doxas, great lume, a bracelet with incredible drape, but a disgrace of a clasp and a tall case.

Ticks every box for £271, with a great bezel and great lume, yet Gethin just doesn't want one.

A handsome, very comfortable 'modern vintage' Pepsi diver with a nicer dial than the SKX007, wrecked only by its horrendous 20-year-old bracelet.

Sapphire, a shimmering emerald dial and a bezel that shames the SKX for under £200: superb, apart from the bracelet and the lume.

An overlooked, discontinued SKX rarity that Gethin loves, irritating 7S26 and all.

A special-occasions watch with a 'mental' dial from Seiko, 'the kings of dials'.

A super-domed, in-house, beautiful dress watch for under £100. Shame about the 21 mm lugs and the strap.

An almost perfect watch and one of Seiko's finest masterpieces; not worth £1,100 new, but a steal used at £750-850.

Not many negatives: a slim, comfortable, workmanlike Turtle that's a better watch in every way than the big one. Buy it used.

An 'ingenious, inexpensive, magnificent' calendar watch for about £100, and the one he says he'll die with.
