WATCHES

Sif Jakobs watches are crafted in 316L stainless steel – both the case and the bracelet – making them durable and hypoallergenic.

All watches feature:

  • 316L stainless steel
  • Hypoallergenic materials
  • Sapphire crystal (extremely hard and scratch-resistant)
  • MIYOTA Japanese movement
  • IP/Ion gold plating (0.5 MIC TIN + 0.1 MIC AU (1N14))

Sapphire crystal is considered the most durable material for protecting the watch dial from impacts and scratches.

UNIVERSAL JEWELLERY CARE TIPS

To preserve the beauty and finish of your jewellery, we recommend following a few simple principles:

Always make your jewellery the last thing you put on – and the first thing you take off.

AVOID CHEMICALS

Avoid contact with perfume, hairspray, hand sanitizer, lotions, and cleaning products, as chemicals can affect metals, plating, and stones over time.

AVOID WATER AND MOISTURE

Remove your jewellery before showering, swimming, exercising, gardening, or other water-related activities. Chlorine, moisture, and sweat can affect metals, coatings, and natural materials such as pearls.

CLEANING

Wipe your jewellery with a soft cloth after use.

If needed, rhodium- and gold-plated jewellery can be cleaned in lukewarm water with a small amount of pH-neutral soap. Rinse thoroughly and dry gently with a soft cloth.

STORAGE

Always store jewellery separately to avoid scratches – preferably in the original box or in a jewellery box with individual compartments.

FREQUENTLY ASKED QUESTIONS

CAN I SHOWER WITH MY JEWELLERY?

No, we recommend that you take off your jewelry before bathing, showering, taking a bath, going to the sauna, or using a sunbed. Steam, moisture, fragrances, and chemicals in soap and shampoo can cause materials to tarnish and become dull

CAN I WEAR MY JEWELRY WHILE WORKING OUT?

We recommend that you remove your jewelry before exercising. Sweat and alcohol in deodorants and disinfectants can react with metals, pearls, or stones, causing color loss and dullness. Chlorine and salt can also damage metals, so you should not wear your jewelry while swimming. There is also a risk of damaging the jewelry if worn during physical activity.

HOW OFTEN SHOULD I CLEAN MY JEWELLERY?

You should clean the jewelry you wear every day approximately once a week and other jewelry in your jewelry box about once a month.

HOW CAN I REPAIR THE CLASPS ON MY EARRINGS?

Earrings can be difficult to close if the clasp becomes bent during use. This can be easily remedied by gently pressing on the clasp, either upward or downward, to make it click back into place.
