All good, watch working fine. Just put it in so not sure about longevity.

I have always been an avid watch wearer and am very pleased when I find the right one to suit my needs. Of course, with smart watches bouncing onto the market recently which can simply be recharged via Micro-USB cable, or the Apple watch connecting directly to your iPhone, one can say that it has somewhat left the quartz watch redundant. I disagree with this statement, as there are so many varieties, shapes, sizes and functions that battery-powered watches cater for still.I am a healthcare assistant and use Prince London New York fob watches when wearing my uniform at work. Additionally, I have acquired a lot of Casio watches over the years. Wearing such watches, especially for work purposes, enables me to keep an eye on the time during shift hours and throughout the day. Therefore, I need to make sure that my watch batteries are of high calibre and I can rely on them to function for more than just a few weeks at a time.Duracell are probably the leading brand of batteries in the UK; especially in the United States. Having tried a variety of battery sizes in pound shops that advertise 20 for £1.00 and failing miserably in the process, I decided to stick to what the statistics show; i.e. keeping to a reputable brand name that has solid roots in the US since the 1920s for its making of components for military equipment during wartime. Over the years, Duracell has become a household brand name and is instantly recognisable via its very popular advertising mascot with the Duracell bunny. Its logo is a brand that has come to be trusted and has the tagline ‘Long Lasting Power Guaranteed’.For the HCA fob watches that I use, the correct battery to be used is a 1.5V 377 Silver Oxide variety. This is coded as D377/V377/SR66. It is a very small-rounded silver battery so you need to be careful when opening up the packaging not to lose it by dropping or misplacing it. You will find the Duracell logo etched onto it, along with the 377 code to identify it, as well as the +side facing up so you know in which way to insert it. You do need to be very sturdy of hand when changing such batteries of course; however, by simply following your manufacturer’s instructions, it is fairly straight forward to insert correctly.The Duracell D377 battery is not rechargeable and if you have a relatively cheap product in terms of price, it may be easier for you to simply purchase a replacement model when the time comes. However, I am rather fond of my work watches, and I wouldn’t use any other type of brand when having to replace my watch batteries. Duracell now utilise 0% mercury in their D377 watch batteries which makes their use a lot safer for you and the environment. Overall, I would highly recommend this 2xpack above more cheaper variants on the market for their sheer reliability to last longer.

Arrived on time and as discribed
