Audemars Piguet unveils world’s thinnest calendar wristwatch

With a movement of 2.89 mm in thickness and a case of 6.3 mm in height, Audemars Piguet’s Royal Oak Self-winding Perpetual Calendar Ultra-Thin has become the world’s thinnest automatic perpetual calendar wristwatch, marking the Swiss brand’s latest technological milestone. 

The manufacture’s R&D team has integrated movement development, design and ergonomics in the conception of this new timepiece to boost its efficiency, robustness and reliability. The result is an ultra-thin self-winding perpetual calendar wristwatch equipped with a complex movement re-engineered to integrate an ultra-thin case, perfectly fitting under the sleeve of a shirt and endowed with a refined dial design enhancing visibility.

To reach an ultra-thin movement of 2.89 mm in height, the perpetual calendar functions, normally arranged on three levels, have been merged into one single layer. This led to the development of two patented innovations: The end-of-the-month cam has been integrated with the date wheel, while the month cam has been combined with the month wheel. The geometry of each component has also been optimized from the onset, reducing adjustment and assembly time. The dial, too, has been redesigned compared to previous Royal Oak Perpetual Calendar models. The day, date and month sub-dials have been enlarged for optimum legibility, while the night and day indication at 8 o’clock has been added symmetrically to the leap year indication positioned at 4 o’clock.

Evolving from the initial 950 platinum RD#2 prototype presented in 2018 at the Salon International de la Haute Horlogerie, the new timepiece combines titanium and 950 platinum for an elegant look and a lighter feel on the wrist. 

Audemars Piguet is one of the oldest Swiss manufacturers of luxury mechanical watches and clocks.


Robotic-assisted surgery at JHAH a first for Kingdom

Robotic-assisted surgery at JHAH a first for Kingdom

Johns Hopkins Aramco Healthcare (JHAH) has become the first hospital in Saudi Arabia to perform a robotic-assisted hysterectomy using fluorescent dye.

“The precision achieved through the use of robotic-assisted surgery has multiple benefits for patients,” said Dr. Turky Al-Rujaib, JHAH gynecologic oncologist, who along with Dr. Fahad Al-Mulhim, gynecologist, performed the procedure for endometrial cancer. “Women whose hysterectomies are robotic-assisted surgeries have less pain and blood loss, shorter hospital stays, require fewer narcotics and recover more quickly.”

JHAH’s robotic surgery program began in December 2016 when Dr. Tareq M. Al-Tartir, JHAH sub-specialist surgeon, and his team collaborated with Dr. Mohamad Allaf, professor of urology, oncology and biomedical engineering at Johns Hopkins School of Medicine (JHSoM) and director of minimally invasive urology, and his team. They jointly conducted the first surgeries in the Kingdom using the da Vinci Xi robotic surgical system. The program has since expanded and includes gynecological surgeries and bariatric surgery.

“This successful operation could not have been done without the support of the JHAH robotic team,” said Dr. Al-Mulhim. “We are pleased to report the patient is recovering well. This is a tremendous achievement that going forward will improve the outcomes for many of our patients here at JHAH.”

The robot’s “hands” have a high degree of dexterity, allowing surgeons the ability to operate in very tight spaces, for example the pelvis, that would otherwise only be accessible through open surgery with long incisions. Life after surgery is improved with this technique as there is minimal scarring, fewer postoperative complications and often a faster return to normal activities. 

JHAH is the result of a joint venture between Saudi Aramco, a world leader in energy, and Johns Hopkins Medicine, one of the world’s leading academic health systems. This health care organization is designed to drive and enhance the well-being of the community in an environment of growth and learning, by providing innovative, integrated and patient-centered care to Saudi Aramco’s employees and health care beneficiaries.
