Aragon have released some special pricing for their Divemaster range with titanium cases on rubber straps. Despite them being large watches the 45mm only weighs 3.4 oz (96g), and the 50mm is 4.2 oz (120g). You also get sapphire glass and decent water resistance with a screw-down crown, and the 50mm comes with an extra long strap for large wrists.
There's a choice of NH35 movement for a basic three-hander (45mm & 50mm) or NH34 for GMT function (50mm only), both with date windows at 3 o'clock. Quite a range of colourways, too: black, blue, green, purple, yellow, pink, and teal.
Edit: I changed the link above to a single watch so it gets a better thumbnail, click here to see the whole range.
As usual, if you use a credit card with no international fees you'll avoid extra charges.

It weighs even less, if that matters, at 85 grams.
