We recently reached out to some of the luxury industry's most prominent professionals and asked them a simple question: "What's your favorite luxury watch of all time, and why?" From watchmakers and jewelers to bloggers and stylists, their responses were both intriguing and enlightening!

"I have selected a Breguet timepiece, the model Breguet CLASSIQUE 5317 Tourbillon. (http://www.presentwatch.com/breguet/103318.html) I made this choice because I think it is a classic and timeless timepiece (as almost all Breguet models are, in my humble opinion) but with a beautiful tourbillon, hours, minutes and an outstanding - and pretty unusual - power reserve at 12:00am/pm" - Julien Seux, Present Watch (@PresentWatch)

"There are so many great ones to choose from but [I am] partial to the Piaget Rose Limelight Garden Party watch. Timeless beauty!" - Angela Tunner, Eat Love Savor Magazine (@AngelaTLuxury)

"My favourite has to be Frank Muller for design,craftsmanship and the wow factor. King Conquistador Cortez is my fav. Tap." - Terry Pearce (@tapterry455)

"That’s a tough question to answer for someone like myself. I see so many fabulous watches, it’s hard to pick just one favorite watch. But, I will say some of my favorite brands are Audemars Piguet, Breguet, Franck Muller, and Patek Philippe." - Roger Kuo, The Finest Watches (@TheFinestWatch)

"In just a few words? :) AP Royal Oak 15202. A luxury sports watch in stainless steel with superb movement and finish." - Robert-Jan Broer, Fratello Watches (@robertjanb)

"Do I really need to choose just one? Really hard decision given my awareness of watches. I love sport pieces and divers the most, but also craftsmanship. If it is a well-made dive watch with a beautiful movement and a refined design it will steal my heart. There are perhaps 1-2 dozen brands that consistently make those. I also like some classic brands like Lange." - Ariel Adams, aBlogtoWatch (@aBlogtoWatch)

"Mine is @Longines because I own one that my wife gave me when we got married." - Paul Johnson, A Luxury Travel Blog (@luxury__travel)

"Cuervo y Sobrinos Robusto is up there... call me a sucker for hand rolled cigars from the thighs of maidens & the Havana vibe" - Christopher Ward, the Christopher Ward Watch Company (@ChrisWardLondon)

"We love this vintage ruby and sapphire Tourneau watch. It's perfectly delicate but made to last. http://bit.ly/10XnBlw" - The staff at SHK Magazine (@SHKmagazine)

"As a versatile and timeless investment piece, this @Patek_Philippe Nautilus 5712G tops our list. pic.twitter.com/HQ84DmbP" - The staff at PROCURATEUR (@PROCURATEUR)

"Wow, hard to pick just one! Between a Rolex 16808, AP Concept Tourbillon 1, Patek 5980R, MCT Sequential 1, I could go on.. :) Why: Rolex because it's timeless, AP was a landmark piece, Patek because its the ultimate marque & MCT is just crazy!" - Anish, Watch Anish (@WatchAnish)

"My all time favourite is my father's Cartier Tank. It is classic, elegant and light on my wrist. A piece for all occasions." - Zeina Dakak (@zluxe)

"Rolex Submariner, it is just a Classic." - Billy, California Custom Coach (@tweet_billy)

"Even if it is very hard to select only one timepiece, and in the meantime one brand, I have selected as my favorite watch the FP. Journe CHRONOMÈTRE OPTIMUM PLATINUM. (http://www.presentwatch.com/fp-journe/801479.html) FP. Journe is one of my favorite brands, and I also think they use great movements and the technical details are simply awesome. They manufacture "classic" high-end watches but with a modern touch." - José Sousa, Present Watch (@PresentWatch)

"The sundial!" - Antonio Centeno, Real Men Real Style (@RMRStyle)

"I don't think any genuine watch fan could answer that. It's like asking a movie fan to name just one 'favourite' film." - The Prodigal Fool, The Prodigal Guide (@TheProdigalFool)

"hmm that is hard! Love this [Vacheron Constantin Patrimony Traditionnelle] because of the unique band! http://www.tourneau.com/shop/brand/vacheron-constantin/rvids/4657#pdpSeoKey!shop_brand_vacheron-constantin_patrimony-traditionnelle-53434p" - Brittany Mills, B Culture Media (@bculture_britt)

"Impossible to answer. Part of being a luxury watch collector is never being fulfilled and also searching for a new favorite." - The staff at KeepTheTime Watches (@KeepTheTime)

"De Bethune DB28. Timeless design paired with innovation, useful complication, wearability, + from an independent watchmaker." - The Watchman (@eurowatch)
