Great daily wear watch, wears smaller and lighter on the wrist so it doesnt feel like i am wearing a watch. I also work a manual labour job so it is perfect as I dont think it will be getting damaged at work.

Great stealthy looking Casio aka Casioak

Love this G-shock for number of reasons:
- Blacked out colour but still a practical & legible time piece
- Thin and light weight
- Price!

This watch has been surprisingly popular world wide and left a heap of shortage most suppliers. I'm glad to be able to grab one from Shiels and was shipped out very very fast.

It isn't easy to find a jeweller you can rely on. Buying a diamond ring or gold pendant means wanting confidence that your money is well spent and that you're getting something that lives up to the promises. It's common for bold claims to disappoint, as the craftsmanship and cost don't always add up. That's why peace of mind matters as much as the sparkle. Since 1945, Shiels has built a name on affordability and quality, offering beautiful pieces backed by trust and reliability. You can always be certain about who you're purchasing from and exactly what you're spending, with no surprises or hidden fees. Each item is selected by our in-house jewellery hunters, who search for the newest, most beautifully made designs you won't see anywhere else.

Milestones can feel lacking without the right jewellery, which is why variety is so important. With Shiels, you have access to a wide variety of lovely rings, earrings, necklaces, pendants, chains, bracelets, bangles and anklets.

Moreover, we provide jewellery in gold-plated, silver, and stainless steel, on top of the yellow, white and rose gold choices you can select from. For birthdays, our collections feature vibrant gemstones and charm bracelets that highlight a recipient's individuality. On the other hand, you could opt for a diamond eternity band or a finely crafted pendant as a symbol of timeless love if you have an upcoming anniversary. You want to know your choice feels significant and purposeful, whatever the occasion. Whether you're considering 9ct Yellow Gold Silver Filled Diamond Cut Curb 100Gauge 60cm Chain, Sterling Silver Gold Plated Ribbed 3/4th Hoop Earrings, Seiko Presage Cocktail Time SRPB46J Automatic or something else, we make it possible to match your gift to the importance of the event or recipient.
