All about the YEMA Skin Diver Slim CMM.20 12.24.99.SN.M3 diving watch

Iconic design in a modern form

With the new Skin Diver, the legendary Superman line presents itself in a contemporary guise that sets new standards both technically and visually. The 39.5 mm brushed stainless steel case not only offers a classic presence on the wrist but combines robustness with a deliberately understated elegance. The case architecture is complemented by a double-domed sapphire crystal that subtly references the vintage charm of the Superman – while offering modern performance and scratch resistance.

Pre-Order. Shipping from early May. 

For a limited time: Order now and get the grained leather strap for free (see photos).

5 YEARS INTERNATIONAL WARRANTY

As part of YEMA's quality promise, all timepieces with a mechanical movement from YEMA Manufacture receive an extended international warranty of 5 (five) years.

Innovation meets functionality

A significant innovation is the revised Bezel-Lock-System. Unlike the original design, where a visible holding mechanism above the bezel was locked by the crown, the new technology is completely hidden under the sapphire bezel. The result is a noticeably cleaner line design and a noticeably smoother operating comfort. This subtle integration not only gives the timepiece a more reduced profile but also elevates it to a new level of modern watch architecture – without denying its roots as a functional tool watch.

Precision with a French soul

Inside works the new caliber Manufacture Morteau 20, an ultra-thin automatic movement with micro-rotor, completely developed and manufactured in France. Its high accuracy of –3/+7 seconds per day and an impressive power reserve of 70 hours make it the ideal choice for watch enthusiasts who appreciate a combination of reliability and sophistication. The sapphire crystal case back offers a clear view of the finely finished movement details – a tribute to the art of French watchmaking.

Thoughtful wearing experience

The newly developed Scales Slim Bracelet emphasizes the overall look with a uniformly brushed finish that seamlessly merges with the case. The fine tapering to only 4 mm towards the clasp ensures harmonious proportions and an especially comfortable wearing experience that naturally adapts to every wrist shape.

Comfort at the push of a button

A highlight is the adaptive Micro-Adjustment-System in the clasp. The last link connection slides on a precisely milled guide rail and allows fine adjustment of the bracelet in 1-mm increments up to 6 mm. Thanks to the intuitive double pusher, the length can be adjusted at any time and without tools – whether in heat, activity, or throughout the day. The entire mechanism remains securely hidden inside the clasp and is thus optimally protected from external influences.

FAQs

About me

My name is David, I was born in the late 60s in NRW, now live and work in the beautiful Harz Mountains, and have been running this watch shop, among other things, since spring 2022.

Since 2018, I have also been running my watch blog watchdavid.de, which features hundreds of reviews and watch news. Since then, I have taken thousands of professional watch photos for over 100 watch brands. Many photos can be found in my reviews. I am known worldwide for this.

As a result, I naturally had thousands of watches in my hands. And with this shop, I want to bring you closer to watches that have convinced me in many ways.

So come along on a journey full of watches... off the mainstream... and if you have a question, please feel free to ask me anytime via the form, chat, WhatsApp, email or phone.

I am very much looking forward to meeting you.

PS: My hobbies & passions include the internet (first agency already in 1996), Denmark, France's coasts (Brittany, Normandy & Côte d’Azur), hiking, e-MTB, sales (Bachelor of Sales) and photography.

My Achilles' heel includes children's chocolate, good food, sneakers & of course watches... :-)

Shipping & Insurance

Within Germany and the EU, I ship free of charge. Shipping is done via DHL and insured up to 500€, 2,500€, or 25,000€, depending on the watch value. The watches are thus always sufficiently insured.

The delivery time can be found in the description and/or under the shopping cart button. Some watches are only produced after ordering, others are brand new and, for example, only available in a few weeks (so-called PRE-SALE), etc...

Cancellation & Return Shipping

You can cancel your purchase within 14 days of receiving the goods.

I will cover the costs for the return shipping for you.

IMPORTANT: Do not send the watch back yourself, I will send you the free return label.

Please simply contact me for this. david@watchdavid.com

It is also important that the watch is unworn and free of signs of use. After successful inspection, I will refund you the purchase price. The refund will be made using the same payment method you used for the purchase.

Authenticity & Condition of the Watches

I guarantee you that all watches I offer are exclusively new original products. The watches come directly from the manufacturer and have had no previous owners, unless I explicitly point this out (e.g. so-called PHOTO WATCHES).

As an official dealer, I offer you exclusively authentic products. These are offered in the original packaging, with warranty card, etc., just as they are delivered by the dealer. Everything in the so-called full set. One delivers more, another less...

Warranty & Service

All watches purchased from me come with the international manufacturer's warranty, which usually lasts two years. Some brands even offer a warranty of up to 5 years.

If a warranty case occurs, I will take care of the shipping to the manufacturer or the responsible service center for you and also organize the return shipment to you. In addition, I handle all communication with the manufacturer so that you don't have to worry about anything.

Even after the warranty period has expired, I remain your contact person and support you with service questions or repairs.

No response received?

You wrote to me via the contact form, through the price proposal, directly by email, chat, but you haven't received a reply?

Then please check your SPAM folder! Many providers are getting crazier and pushing more and more into spam.

I usually answer every inquiry within 24 hours at the latest. On weekends, it can sometimes take a bit longer. As a rule, I respond within a few minutes or hours.

Something can slip past me sometimes too. Or the technology doesn't work as it should. Feel free to write to me again at david@watchdavid.com

Mechanics - Sometimes things can happen there too

Before I ship your order, I carefully check each watch for visible defects.

If a problem should occur, such as damage during transport, please inform me immediately. I will do everything possible to quickly find a solution and ensure that you are satisfied.

My goal is to offer you not only high-quality products but also a first-class shopping experience. I look forward to welcoming you as a satisfied customer!

More questions? About the watch? Something else?
