Nixon Sentry Solar A1346-510 Unisex 40mm Gold-Tone Solar Day-Date Watch – Black Dial, Gold Stainless Steel Bracelet

Nixon Sentry Solar Stainless Steel A1346-510: Gold-Tone Steel with a Black Dial

The Nixon Sentry Solar A1346-510 is a 40 mm solar-powered watch that pairs a gold-tone stainless steel case and bracelet with a black dial. The colourway is sold under the name All Gold / Black. A Japanese solar quartz movement powers the hands, and the dial adds a day and date display. The water rating is 100 metres. It is a more dressed-up take on the Sentry than the plain steel versions, with a warm metal finish that stands out against the dark face. At 40 mm it is a unisex size, equally at home on a slim man’s wrist or a larger woman’s wrist.

Design and Wrist Presence

The case is solid stainless steel with a gold-tone finish, 40 mm in diameter and about 11.5 mm thick on the Sentry Solar platform. Case and caseback are both steel, and the bracelet matches the case so that the entire watch reads in one metal tone. Because the colour is carried from lug to clasp, the watch looks deliberate and finished rather than mixed. The black dial gives strong contrast, so the hands and indices are easy to read quickly. One listing gives the weight as roughly 124 g, which suggests a watch with genuine substance for its size.

• 40 mm gold-tone steel case – a modest diameter with a rich finish
• All gold / black colourway – metal and dial contrast clearly
• Solid steel construction – case, case back and bracelet
• Approx. 124 g – a reassuring weight on the wrist

The Black Dial

The dial is black and semi-transparent, with an enhanced sunray finish noted by one listing. Applied stainless steel indices stand on the surface, there is an up-printed seconds track, and the day and date appear in a framed window. The hands are steel skeleton hands with lume blocks, and the lume helps with reading the time in low light. Against the gold-tone indices and hands, the black face has a classic gold-on-black feel, which is a combination that works equally well with a dark suit and a plain T-shirt. The Nixon name appears as a wordmark on the dial.

Solar Movement

The movement is an Epson solar-powered Japanese quartz calibre with three hands and a day and date function. A solar cell below the dial turns light into stored power, so you do not need to change a battery in the usual way. Nixon states that around an hour under office lights charges the watch for a full day and that six hours in direct sunlight can store up to six months of running time. For a watch that is worn daily, the cell stays charged without any effort.

• Solar quartz – powered by light, accurate to quartz standards
• Day and date display – shown in a framed window on the dial
• Lumed hands and indices – readable in the evening
• Stored charge – runs for months once fully charged

Crystal

A hardened mineral crystal covers the dial. It stands up well to normal wear, though like all mineral glass it can scratch if it is scraped against a hard edge, so a little care goes a long way in keeping the dial clear.

Bracelet and Clasp

The bracelet is solid stainless steel in the same gold tone as the case, tapering from 20 mm at the lugs to 18 mm at the clasp. It is a free-swing design that attaches using quick-release spring bars, so the bracelet can be removed without special tools. The buckle is a double-locking steel clasp, which holds firmly in daily use. The tapered shape is slimmer near the buckle, making it less bulky under a sleeve. If the bracelet needs resizing, a jeweller can do it in a few minutes.

Water Resistance in Practice

With a 10 ATM rating, equal to 100 metres, the watch is suitable for showering, swimming and snorkelling. It is not made for scuba diving. Make sure the crown is pushed fully in before it gets wet, and avoid pulling it out underwater. A gold-tone finish also benefits from a freshwater rinse after the sea or chlorinated water, followed by drying with a soft cloth.

The Sentry Line and Nixon

Nixon began in California in 1998 and built its name on dependable watches for active people. The Sentry is among its best-known models, and the solar versions bring a modern power source into a familiar case. The All Gold / Black version is an example of how the same dependable platform can be dressed in a more polished finish.

Who This Watch Suits

• Wearers who like gold-tone metal paired with a dark dial
• People who want a solar watch that avoids routine battery changes
• Anyone who needs day and date and a 100 metre rating in a 40 mm size
• Buyers choosing a gift who want something distinctive but practical

The sources describe this model with some variation between men’s and women’s labels. Based on its 40 mm case it is best treated as unisex.

Care and Maintenance

Wipe the watch with a soft, slightly damp cloth and dry it fully. Avoid abrasive cleaners, which can wear a gold-tone finish over time. Give the watch regular exposure to daylight so the solar cell stays charged, and avoid storing it in the dark for long periods. If you wear it in the sea or pool, rinse it afterwards with fresh water, and have a watchmaker check the seals now and then to keep the water resistance reliable.
