Quick answer
Of the six luxury watches in this guide, our top pick is the Omega Seamaster Diver 300M Automatic 210.32.42.20.01.001: a 42 mm stainless steel case, 300 m water resistance and a sapphire crystal, as listed on Amazon.com.au on 23 October 2026.
This guide was written from the products’ Amazon.com.au listings as they read on . Listings change, so check the details on Amazon before you buy.
The one to start with: a 300 m diver with a sapphire crystal, sold by CW Watches AU with change of mind returns when we checked, and a listing whose movement rows agree with each other.
The six watches here are compared on case size, water resistance, strap and what each listing says about the movement. There are two 300 m divers, a tonneau-shaped bracelet watch, a 10 mm thick blue-dial watch on a steel bracelet, a field watch on canvas and an open heart dial. Every listing puts the watch in the men's department, though Certina's description says its DS Action range is for men and women. All six were listed on Amazon.com.au with a buy button when we read the listings on 23 October 2026, and every case size, water resistance figure and dimension below is taken from the product's own listing.

How to choose the best luxury watches in Australia
1Check the water resistance against what you will do in the water. The Omega Seamaster and the Certina DS Action Diver both list 300 m, and Certina's listing says it is 'suitable for diving and/or snorkeling'. The Tissot PRX lists 100 m but its listing says 'no diving or snorkeling'. The Hamilton Khaki Field lists 50 m, and the Seiko Presage listing gives no water resistance figure.
2Look at case size and thickness. The Hamilton Khaki Field is listed at 38 mm across and 9.5 mm thick, the smallest and thinnest of the six. The Certina DS Action Diver is the widest at 43 mm, and the Omega Seamaster is the thickest at 13.6 mm.
3Choose the strap. The Omega Seamaster comes on a rubber strap and the Hamilton on a canvas strap, both with a buckle. The Certina, Tissot, Raymond Weil and Seiko are on metal bracelets.
4Read the movement rows carefully. The Raymond Weil and Certina tables list the power source as 'Battery Powered', while the Certina's bullets and the Raymond Weil's title and description describe automatic movements. The Hamilton is called 'Mechanical' in its title, 'Handwinding' in its description and 'Automatic' in its table.
5Check the seller and warranty. Five of the six are sold by CW Watches AU, and their buy boxes said they were eligible for change of mind returns; the Raymond Weil was sold by Amazon UK when we checked. Only the Raymond Weil and Certina listings state a warranty term, 2 years each.
Editor's note
Three things separate these watches. The first is water: the Omega Seamaster and Certina DS Action Diver list 300 m, the Tissot PRX and Raymond Weil 100 m, the Hamilton 50 m, and the Seiko gives no figure. The second is size, from the Hamilton's 38 mm, 9.5 mm thick case to the Certina's 43 mm and the Omega's 13.6 mm. The third is how consistent the listing is: the Raymond Weil, Certina and Hamilton tables list 'Battery Powered' against movements described elsewhere as automatic or mechanical, so read the bullets and description as well as the table. Listings were read on 23 October 2026 and can change.
