Description
The Rado Florence Open Heart is a unisex Swiss automatic dress watch built around a black embossed dial and a slim, polished steel profile. It suits anyone who wants a refined everyday piece with a mechanical heart.
The 39mm stainless steel case measures 11mm thick and combines brushed and polished surfaces under a curved sapphire crystal. The automatic Swiss movement carries an antimagnetic Nivachron hairspring and delivers an 80 hour power reserve, while water resistance is rated at 50 metres.
The stainless steel bracelet alternates polished middle links and closes with a 3-fold foldover clasp. Rhodium-colored applied hour indexes stand out against the embossed black dial, which keeps the watch easy to read and easy to dress up or down.
Frequently Asked Questions
Can I wear the Rado Florence Open Heart in the shower?
It is rated to 5 bar, or 50 metres, which covers splashes and rain. Hot showers and swimming are best avoided, as steam and pressure can stress the gaskets over time. For daily wear at a desk or out and about, the Florence Open Heart is perfectly fine.
How long does it run if I leave it on the shelf?
The automatic Swiss movement stores an 80 hour power reserve, so it typically keeps running for more than three days off the wrist. A weekend away will not stop it, though you may need to reset the time after longer breaks.
Will it fit a smaller wrist?
The case is 39mm across and 11mm thick, with a bracelet that can be sized using its links. Wrists of about 6.5 to 7.5 inches usually suit it well, and the unisex design looks balanced on both smaller and larger wrists.
What is a Nivachron hairspring and why does it matter?
It is an antimagnetic alloy hairspring that resists magnetic fields from phones, laptops and speakers. Rate stability is better preserved in daily life, which is a practical benefit compared with a standard hairspring.
How does it compare with a sport automatic for daily use?
The Florence Open Heart favors looks and slim wear over toughness. Its 50 metre rating and polished finish suit office and evening use, whereas a diver-style sport automatic is a better alternative if you swim or work outdoors.
How often does it need service?
Mechanical watches generally benefit from servicing every five years or so, depending on use. Checking the gaskets periodically is sensible given the 50 metre rating, and a qualified watchmaker can advise on timing.
Editor's take
Rado's Florence line is the brand's slim, dressy corner, and this Open Heart version speaks to buyers who want a unisex Swiss automatic with a bit of visual theatre. At 39mm and 11mm thick it sits comfortably on a wide range of wrists.
The headline spec is the 80 hour power reserve paired with an antimagnetic Nivachron hairspring. That means the watch can sit off the wrist over a weekend and still be running on Monday, and daily magnetic exposure from phones and laptops matters less. The curved sapphire crystal over a brushed and polished stainless steel case adds scratch resistance appropriate to the category.
The trade-off is water resistance. At 50 metres it handles splashes and rain, but it is not a watch for swimming or showering, so anyone wanting an all-weather daily piece should look at a diver-style alternative. The 3-fold clasp is secure, though it offers less fine adjustment than a micro-adjust deployant.
It suits those who prefer a refined, mechanical dress watch with a distinctive embossed black dial and polished bracelet. In a similar price bracket, Swiss dress automatics from Tissot or Longines are worth cross-shopping.
