The 901 RWB Rotana is a limited edition timepiece made from Akira Nakai’s RWB Porsche, ‘Rotana’.

The fruit of a close collaboration between Nakai-san and the RWB team, the 901 RWB Rotana timepiece embodies the signature blend of breathtaking looks and performance that defines RAUH-Welt BEGRIFF. The ROTANA is Nakai-san’s vision taken to the extreme – an outrageously styled purple Porsche 993 with added turbo.

The idea for this evolutionary update to his first project came to him in a flash during a trip to the United Arab Emirates, when a purple Lamborghini shot past him as he walked alongside buildings owned by the Rotana group. The vehicle has since become Nakai-san’s personal race and testbed vehicle.

“RWB isn’t a business, it’s a passion… You need to love what you do.”

– Akira Nakai


Of An Icon


Nakai-san is renowned for his expertise in customizing classic Porsche 911s, specializing in crafting bespoke wide-body kits and extreme fenders.

Regarded as an artist and a subculture icon within the automotive and drifting communities, his RWB conversion projects, meticulously handcrafted, evoke both admiration and controversy.

In contrast to Porsche’s traditional approach of careful and understated modifications to its iconic models, Nakai-san’s unconventional and somewhat chaotic methods stand out.

His unique style leads to a true transformation, where refinement gives way to audaciousness, resulting in cars that undergo a Jekyll-and-Hyde-like evolution, emerging with a radical new identity.


Original Hoods


Despite Nakai-san’s primary focus on transforming classic Porsche 911s into their extreme alter egos, his profound passion for the original cars is evident in his unique practices. He meticulously preserves every hood removed from his own vehicles in his garage in Kashiwa, Japan.

From this collection of original parts, Nakai-san and his team graciously provided us with remnants leftover from their conversion projects. These parts were meticulously repurposed into watch dials, ensuring that the essence of the iconic Porsches lives on.

Each dial is treated with a transparent lacquer, preserving its authenticity and integrating it into the distinctive design of the 901-RWB Rotana timepiece. This marks the culmination of their extraordinary transformative journey.

Capturing the essence of RAUH-Welt Begriff and Nakai-san’s artistic vision, a limited edition of just 305 watches has been crafted, embodying the spirit of innovation and dedication that defines his work.

A two year



The REC x RWB project spanned two years, marking a significant departure from the traditional Porsche realm that this car embodies.

Capturing the essence and character of the vehicle posed a formidable challenge, requiring constant adjustments throughout the project to achieve the desired outcome.

Sporting a 44 mm case, the 901 RWB Rotana pays homage to the extreme wide-body kit with its electrifying black-and-purple color scheme and stylish hubcaps.

The sandwich dial showcases month and day indications at 3 and 9 o’clock, respectively, featuring Japanese characters as a nod to Nakai-san’s homeland.

Crafted for optimal wrist comfort, the 901 RWB Rotana boasts an ultra-flexible FKM Viton black rubber strap, ensuring a superior wearing experience.

You can purchase this item in payment installments with Splitit - with no extra hidden costs. The installments will be spread over your chosen number of months and debited to your credit card.
Splitit installment payments at 0% interest: How does it work exactly?

Splitit allows you to split the total payment over a maximum of twelve months using your credit card. This service is free, involves no credit checks or applications, and means you can choose to split your payment into monthly installments.

To use this payment method all you need a credit card with a sufficient amount of available credit. Splitit authorizes the total order value—but don’t worry, this is not taken in full when you complete the purchase. At the time of shipping, only the first installment will be charged to your credit card. The remaining balance will be held on your credit card until the final payment has been made. However, a payment authorization for the outstanding amount of your purchase will be held during the full payment period.

After each monthly payment, the amount held from your available balance will be reduced to the new remaining balance (the held amount might appear as “pending”). To ensure that the authorization of your credit card is valid for the entire payment period, the authorization will be renewed every 21 days.

Are there any extra fees involved?

No, this is an interest-free payment method with no additional fixed fees, service fees, interest, or hidden fees of any kind.

Which credit cards does Splitit support?

You can pay using Splitit with a Mastercard or Visa card. Debit cards, American Express and pre-paid cards are not accepted.

Do I have to maintain the required available credit amount on my credit card?

Yes, you must maintain a sufficient amount on your credit card for both the monthly payment and for the full outstanding amount of your purchase during the full period of the plan. The authorized amount will be charged only in the event that a monthly payment is declined (the authorization hold might appear as “pending” on your credit card bill).

What happens if I return the product?

If you decide to not keep the ordered item(s), upon return of the items we will reimburse the installments that have already been paid and cancel the outstanding payments.

When and where can I choose the number of installments for my payment plan?

Installment payments with Splitit can be chosen as a payment option during the checkout process. Here, you can choose the number of installments in your payment plan and view the monthly payment amounts.
