Introduced at Baselworld 2012 back in March, the Omega Speedmaster Racing, is a more affordable version of the brand's Co-Axial Speedmaster.

Instead of utilizing Omega's new in-house manufacture Co-Axial caliber 9300 which we discussed here.The Speedmaster Racing is powered by exclusive self-winding chronograph movement - caliber 3300. Caliber 3300 is considerably more affordable than the 9300, yet it still features Omega's proprietary Co-Axial escapement with 3 levels, a Si14 silicon balance spring, NIVACHOC shock absorber and a column-wheel chronograph mechanism. It has 31 jewels, runs at 28,800 vph (4Hz) and a power-reserve of 52-hours. Moreover, it is an officially certified chronometer.

Today, Elie and Pierre Bernheim, grandsons of Raymond Weil, have announced a new watch accessibly priced (sub-$1,000) Swiss watch brand - 88 Rue du Rhone. Named after the famous shopping street in Geneva (similar to Fifth Avenue). The first watch designs will be unveiled at JCK in Las Vegas next month.

"The launch collection is comprised of both female and gents pieces ranging in size from 29mm to 42mm with both quartz and automatic movements. The brand's name comes from the famous and prestigious street in the city of Geneva, which mirrors the name of the city's river. The signature logo engrained in the design of the collection bears the number 88, encompassing the ideology of good fortune and representing infinity."

The Deep Sea Chronograph function indicator was inspired by a 1953 Jaeger Chronolight dashboard instrument (shown above).

Jaeger-LeCoultre has just revealed a new diving chronograph, the Jaeger-LeCoultre Deep Sea Chronograph. Unlike most chronographs, this one can be operated underwater. Breitling makes a magnetic quartz based chronograph that operates underwater, but as far as mechanical chronographs go, they typically do not work underwater.

The movement is a Swiss quartz (ETA G10.211); functions include hours, minutes, seconds, chronograph (1/10th of a second precision) and date (at 4 o'clock).

Steel screwed-down crown fluted with RW logo and steel screwed down fluted pushers. The dial is galvanic black, with a central checkered motif pattern in the center.

At Baselworld 2012, Victorinox unveiled the redesigned Dive Master 500 collection.

The Dive Master 500 comes in either 38 mm or 43 mm diameter stainless steel cases - treated with either Black Ice of gold PVD. There are four 38 mm quartz models: black, burgundy, khaki green (with gold PVD coating) or white; two 43 mm quartz models in white or khaki green; and three 43 mm mechanical versions: grey, red or brown. The quartz models are powered by Swiss made Ronda 715.5 calibers and the self-winding models are powered by the ETA 2892-A2 caliber (automatic has clear case back).

LIP Blancpain watches were not the first dive watches on the market when they were introduced in 1953. They were, however, the most modern dive wristwatches at that time. The reliability and compactness of Fifty Fathoms models, which were originally designed for military use, became legendary. The reputation earned them the right to be used by armies such as French Navy, Czech, Polish, German federal, some Nordic countries, and also by the US Navy (SEAL, under water demolition team, Frogman).

On May 2, 2012 - at the Adour Alain Ducasse Restaurant inside the St. Regis Hotel, New York City - the Foundation de la Haute Horlogerie (FHH) hosted an exclusive cocktail reception to celebrate the North American launch of the The Mastery of Time written by Dominique Fléchon, a French author, historian and expert on fine watchmaking. The book was presented by author and historian Nick Foulkes.

The Grand Seiko GMT Anniversary Edition celebrates the tenth year of the GMT timepiece. The GMT uses the caliber 9S66A, which is the same movement originally used a decade ago. It features striped bridges, 35 jewels, a frequency of 28,800 vph (4Hz) and a 72-hour power reserve. A circular blue titanium/tungsten blue rotor with cut-outs is visible through the clear caseback and is signed with the Grand Seiko logo. According to Seiko, the rotor has high elasticity which absorbs vibration and shock "ten times better" than brass. Functions include hours, minutes seconds date and second time zone (GMT). The bright blue dial has applied steel indexes, Dauphine-shaped steel hands and a gold-toned GMT hand.

This is the Maurice de Mauriac Zurich Chronograph Modern in a 42 mm x 14 mm satin brushed finish titanium case. We previously reviewed a 45 mm diameter black DLC (Diamond Like Carbon) case variant here. The majority of Maurice de Mauriac timepieces come with beautiful satin brushed cases which are - both harder to finish than a typical brushed finish and easier to scratch. Nevertheless, I highly recommend the satin finish as it looks great even with scratches.

Last month, Richard Mille hosted a dinner in New York City to honor Natalie Portman, and welcome her as a friend of the brand. "For the occasion, Natalie chose to wear a conflict free diamond-set version of Richard Mille's original watch for women: the RM 007 Automatic. With both natural rubber and synthetic satin strap options according to Natalie's wishes, the RM 007 fits easily into Natalie's lifestyle, whether she is at home with her family, traveling, or attending a glamorous event."
