What time is it? Watches and horology

Neither, ffs.

You want one of these;

The Kaventsmann Abyssos.

Case diameter, height and weight have become a little bit of an obsession recently, so its 50mm round, 26mm high, and weighs 290 grammes.

290 grammes.

The Air King you are looking for will weigh 45 grammes.

No, I meant you should buy this light one...
