Watch of the Week: Seiko’s Prospex SLA055 Is Tough Enough for Antarctica

Published

Seiko SLA055 watch


If you’re looking to really put a watch to the test, send it to Antarctica: If it can survive the continent’s frigid temps, howling winds, snow, and ice, then it can survive anywhere. The strategy worked well enough for Seiko, at least. Members of the Japanese Antarctic Research Expedition wore Seiko divers for the first time in 1966. Now, the brand has released the limited-edition Seiko Prospex SLA055, a new dive watch that builds on its predecessors’ impressive pedigree.

Seiko released its first dive watch in 1965, and it featured water resistance down to 150 meters and an automatic movement. In 1966, members of the 8th Japanese Antarctic Research Expedition wore this rugged watch on their journey to Antarctica, and it set the standard for Seiko divers to follow. The Japanese Antarctic Research Expedition was so impressed with the watch, it chose Seiko divers for its subsequent missions in 1967, ’68, and ’69. In 1968, Seiko set the bar even higher with the release of a new diver that offered 300 meters of water resistance and a more robust automatic movement. The new Prospex SLA055 is based on that iconic timepiece.

The new watch combines a tough design with handsome accents that reference Seiko’s long history in Antarctica. The 42.6mm case, bezel, and crown of the SLA055 are made from Seiko’s proprietary Ever-Brilliant steel, a type of stainless steel that offers improved corrosion resistance over the types of steel commonly used in other watches. It also includes unique design elements to make it easier to use in the cold—and more durable: The bezel has large notched edges to make it easier to grip with gloves, and the crown screws into a separate component (not the case itself), which makes it simpler to replace.

But it’s not all function over form: The watch has some unique design accents that highlight its history and keep it from looking too utilitarian. The dial is a particular standout. It features a subtle pattern that transitions from deep to light blue, a color scheme that evokes the ice sheets of Antarctica. That icy blue is echoed in the numerals and markers on the bezel as well. All twelve of the watch’s hour markers, as well as the hands, are coated in Lumibrite for excellent legibility above and below the waves.

Even the strap is special. It features a chunky block texture that recalls the strap found on the 1968 original, although this modern one is crafted from silicone for excellent durability and comfort on the wrist.

On the inside, the Seiko Prospex SLA055 is powered by an 8L35 automatic movement (developed specifically for dive watches) that’s hand-assembled in northern Japan. Once put together, the watch offers 200 meters of water resistance for underwater adventures, plus a generous 50-hour power reserve for accurate timekeeping. And just like its forebears, it’s heading to Antarctica: It’ll be worn by members of the 63rd Japanese Antarctic Research Expedition, where it’ll surely take a beating and keep right on ticking.

Best Time-Under-Tension Workout for Total-Body Strength

Published

on

Barbell Back Squat


The key to 360-degree muscle: 90-degree eccentric isometrics. It might seem like we’re throwing a lot of geometry at you, but the concept behind time under tension (TUT) is simple, says Joel Seedman, PhD, owner of Advanced Human Performance: “Perform the lowering phase of a movement in a slow, controlled fashion, usually 3 to 5 seconds; pause in the stretched position, typically around 90 degrees; then perform the lifting phase in a powerful yet controlled fashion.” Believe us, a time-under-tension workout can humble even seasoned lifters…Eccentric isometrics are like the pressure cooker of training.

“Rather than mindlessly performing slow-tempo reps, you’re using the increased time under tension as a means to fine-tune your body mechanics and alignment, which requires more mental engagement and focus,” Seedman adds.

If you want to forge functional muscle mass and strength while simultaneously bulletproofing the joints and connective tissue, give this 10-move, full-body eccentric isometrics workout a go.

Directions

Perform the following moves as 90-degree eccentric isometrics following the above protocol. Use heavy weight, but not at the detriment of proper form. Rest 60 to 90 seconds between sets and 2 minutes between circuits. Perform once every 2 to 4 days for optimal results.

Stand lunge-length in front of a flat bench, holding heavy dumbbells in each hand by your sides, palms facing in. Rest the ball on top (shoe’s laces) of your right foot behind you on the bench. Slowly lower your body until your front thigh is parallel to the floor. Pause, then drive through your heel to stand. Switch sides after all reps are complete. 2 x 3-4 reps each side

Stand with feet hip-width apart holding dumbbells or kettlebells. Drive right leg up, foot flexed, knee aligned with hip, making a 90-degree angle. Hinge at hips as you slowly lever your torso toward floor, lowering weights and driving right leg back for counterbalance. Hold, then squeeze glutes to reverse. 2 x 3-4 reps each side

A. Pullup

Hang from a pullup bar using an overhand grip with legs extended and feet flexed. Engage lats and draw shoulders down your back, then pull yourself up until chin is higher than hands. Pause at the top, then slowly lower. Pause at bottom, then reset before your next rep. 2-3 x 4-5 reps

B. Kneeling Overhead Barbell Press

Hold a bar with moderate-to-heavy load at shoulder level with forearms perpendicular to floor. Kneel at end of bench with feet flexed to grip edge for support. Inhale, engage your core and glutes, then press the bar overhead, pushing your head forward so it passes your face, exhaling at the top.
Slowly lower until elbows are at 90 degrees, then hold to maintain tension. Begin your next rep from here. 2-3 x 4-5 reps

Circuit 5

A. Dumbbell Pushup

Place hands on dumbbells (this provides greater range of motion) at shoulder width and feet wider than shoulder width with just toes touching the ground. Keep head neutral and hips high to increase tension on core, chest and tris and reduce stress on spine. Slowly lower to the floor. Stop
once elbows hit 90 degrees, pause, then push up to start. 1-2 x 6-8 reps

B. Biceps Curl

Stand with feet hip-width apart with moderate-to-heavy dumbbells in each hand hanging by sides. Engage biceps to curl the weights up, keeping upper arms still. Pause at the top, then lower slowly. Don’t let arms drop all the way down to keep greater time under tension on biceps. 1-2 x 6-8 reps
