LONGINES Hydro Conquest Diver's 300M watches are a great everyday wear watch. This watch is rugged, and fully embellished by Ceramic parts, the Bezel is 100% Scratch proof Ceramic, and so is the clasp. The crown is a screw down version, with a ceramic Longines logo on it, and the Glass is scratch proof Sapphire crystal. Folks this is a solid heavy duty time piece that will continue to wear with superb quality.
The ETA / VALJOUX 7750 movement that powers this time piece is a versatile and time tested battle TANK of a movement, this movement takes a lot of beating, and still goes on working with split second accuracy. I have personally done, in my watchmaker's bench life, thousands of these movement services, in both branded and un-branded movements. The resultant inertia I have had to see for myself, whilst admiring their long lasting beauty, is that with a little bit of factory service standards, this movement service just falls into step, each and every time I do a service with a ETA 7750. It is a peach to service !
More on the LONGINES premise of superb quality, the case works, and the 300M Diver's appellation on this watch are very noteworthy, the 300M case is a solid piece of mechanics, the pushers are a little weird as they have to be pushed at a 45 degree angle, but once you have got the hang of that, the watch is relatively simple to use. The chronograph functionality on a VALJOUX 7750 is simple, effective, and rigorously tough. A great watch to wear everyday.

Please note that we do not ship to *ASIA-AFRICA-S.AMERICA* Do take the time to read up on my GTC page for more information on how to purchase this time piece from us.

Size guide for wristbands

1 | Lug width

The lug width is the width of the strap at the end that is attached to the watch. This is the interior distance between the two lugs (horn-like protrusions) on the watch casing. The strap will fit your watch only if the lug width of the watch is the same width as the strap.

2 | Buckle width

The buckle width is the width of the strap at the buckle end. If you want to keep your watch’s original buckle and replace only the strap, the width of the original buckle must be identical to the strap width. For watches with folding clasps, please choose a strap specially made for your particular clasp.

3 | Strap length

The strap length is the combined length of the short strap side 3A (without buckle) and the long strap side 3B. For metal straps, the length of the strap including the clasp is measured in the closed position.

4 | Strap thickness

Strap thickness is the height of the strap. Many leather straps thin out towards the buckle end, or “taper”. If you want to keep your watch’s original buckle and replace only the strap, the strap thickness must match the height of the original buckle. For watches with folding clasps, please choose a strap specially made for your particular clasp.
