Hi, you'll be perfectly fine. I've taken my watch into jacuzzis and steam baths several times over the years and have never had any problem. There's even this video on youtube where this guy froze his Steel Daytona and it seems that the watch came out unscathed.

Jewelry, Hair and Makeup. Leave any big jewelry or watches at home or stored safely outside of the hot room. They will only become hindrances in the studio and if you take them off in the hot room, you may accidentally leave them behind.

Steam, soap or some components of a hot spring may accelerate the deterioration of water resistance performance.” “Do not wear the watch while taking a bath or a sauna. Steam, soap or some components of a hot spring may accelerate the deterioration of water resistance performance.”

All Rolex wristwatches are waterproof to depths of at least 100 metres for Oyster Perpetual models, and 50 metres for the Perpetual 1908 watch.
From being hit against furniture to being dropped on the ground, your Rolex watch goes through a lot. However, some of the most significant damage it can suffer is water damage.
Every one of Rolex's Oyster models is water resistant to at least 100m. The brand's trio of dive watches – the Submariner, the Sea-Dweller and the Deepsea improve upon that considerably, coming in at 300m, 1,220m and 3,900m respectively.
Check the water resistance rating: Before wearing a Rolex watch while swimming, ensure it has a water resistance rating of 100 meters or more. Watches with lower ratings are not designed for water activities.
There are few things more timeless and enduring than Rolex watches, and these iconic luxury timepieces are among the very few items that can be worn all day, every day, and last for a person's entire life.

The crown is unscrewed. To wind the watch manually, turn the crown clockwise; turning in the other direction has no effect.
Try to avoid tight underwear, especially your bra, to avoid discomfort that can cause tight clothes in the cabin with high temperature and humidity.
Casio has designed a special heat-resistant, moisture-resistant watch that you can wear into a sauna. The coiled wristband mimics the locker key wristbands you get at a traditional Japanese onsen; this design stands off of your wrist, to avoid getting soaked with sweat.
The short answer is that while you can physically bring your phone into a sauna, it is not the best idea. High temperatures and humidity in traditional and infrared saunas can pose risks to electronic devices. Electronic devices like phones are not designed to withstand extreme heat and moisture.
When shopping for hot tubs, many people will ask their dealers “Can I use a hot tub every day?” The short answer is that yes, it is safe to use your hot tub every day. There's a little more maintenance involved than what most people to do if you become a daily user, but it's entirely possible (and even easy, really).
Hot tub lung is an emerging disorder caused by exposure to Mycobacterium avium complex (MAC) organisms contaminating hot tub water. The description of this disorder has been limited to several case reports published since 1997.
You should also shower after using a hot tub to reduce the risk of skin irritation from water chemicals. This is important regardless of whether you have sensitive skin or not. Allowing chemicals to sit on the skin may cause irritation.

THE DEEPEST DEPTHS
Rolex continues to defy underwater pressure by never ceasing to perfect its watches. In 2008, the brand presented the Rolex Deepsea, whose patented case architecture – the Ringlock system – enables it to withstand the pressure at a depth of 3,900 metres (12,800 feet).
Depending on the water temperature, it is recommended that the watch be removed for these types of activities, such as wearing it in a hot tub. For example, heating the watch to elevated temperatures can also lead to increased failure and expand the water seals.
