New improved OS SERIES 12R and 16R
June 15th 2016

New improved OS SERIES 12R and 16R Optimum Time is always reviewing its product ranges to see if we can improve them in any way.

Welcome to the new OS SERIES 1231R and 16318R watches - both know in sailing circles for the design and fantastic functions – including the massive digits in the last 59 seconds of countdown. Those features still stand, but both now feature the latest high contrast dot matrix display with greater detail and an improved contrast, new display features (including even larger digits in the sailing timer function) and last but far from least the new rechargeable battery that will keep your new pride and joy running on and on.

We have not changed the good looking black case and its comfortable silicon strap that you can personalise with a choice of highlight colours on the OS1231R. The smart shiny look of the OS16318R is still at home on deck, in the sailing club, for leisure use and even in the office - with its choice of real leather strap, treated to give water resistance or the soft black silicon strap - these are two serious sailing watches.

The watches come complete with an easy-to-use charger included that will plug into almost any USB socket.

Great looking event watches just got serious
October 28th 2014

OE SERIES 12 & 16 All serious event riders know and use Optimum Time watches. The "Big Yellow Watch" evolved into 7 co-ordinated colours and was quickly joined by the series 14 with the vibration alarm. Now there are two new watches that will help for everyday use both as a wristwatch and a training aid. Using the dot matrix display featured in the series 14 watches, the new series 12 & 16 watches have the benefits of the bespoke eventing functions plus the good looks, the light weight and the soft silicone strap (OE1261) and the amazing style and sophistication of the stainless steel case with both chunky leather strap and interchangeable silicone strap (OE 16618). These watches combine style, practicality and function and will provide a great compact backup on the cross country course too. The massive digits in the last 59 seconds of countdown will certainly be easily seen!

The best looking competitive sailing watch ever?
February 17th 2014

OS223v (Charcoal) and OS224v (Navy) product updates Optimum Time knows its products are No. 1 for serious dinghy sailors, but at the expense of fashion. Our jumbo watches are not for everyday use and the colourfully fashionable Series 2 & 11 are ideal in the clubhouse, but not for the office. The new Series 12 has received plaudits for its design, the interchangeable coloured strap keepers and for its fantastic functions – including the massive digits in the last 59 seconds of countdown... yet despite its great looks people wanted something a little more up-market. Welcome to the all new Series 16, desirable and with the best of our features. Solid and chunky yet not too heavy, shiny and bold, yet is suitably understated and chic, beautiful, yet totally practical. Supplied with both interchangeable straps,the brown real leather strap, treated to give water resistance and the soft black silicon strap, sportier and with perforations to let the skin breath. Ideal for wearing in the sailing club, on a yacht, for leisure use and in the office, yet retaining all the renowned OT functions.... this it is still a serious sailing watch.

OS223v (Charcoal) and OS224v (Navy) product updates
February 5rd 2014

OS223v (Charcoal) and OS224v (Navy) product updatesBack in stock at Optimum Time is the Series 2 watch in both Charcoal and Navy. Last year, the choice was between a normal (soft-touch PU) strap –as on the recent OS 229 pink watch – or a velcro strap which can be worn as an everyday strap, but also can be worn over clothing. This year that choice has been removed and the watch now comes with hexagon screws to give a strong, yet removable, strap fixing. Hexagon keys are provided to ease the interchangeability. The OS223 & OS224 are deleted, and the OS223v & OS224v now come with the added value of both straps in the package. On the new Charcoal, Navy and Pink OS2 series, OT has made changes to the polished stainless steel bezel fixing, including having mechanical and glue fixing. Seals within the button assemblies have been amended to give even higher water resistance.

New rechargeable OE series 14 - A new dot matrix wristwatch for eventers
December 3rd 2013

NEW OE Series 14 Hot on the heels of the new Series 14 sailing watch is the OE Series 14R event watch. The new product has the same new event functions that are in the new OE Series 390. Now the countdown timer gives an audible warning every full minute to go, plus a last 30 second beep sequence that warns of the end of period. Count-up from is still available with minute warnings, but the new big feature is programmable count-up. Put in the course time, press start, then see as the watch heads for that time – still with a beep every minute gone, but with a last 30 second warning beep sequence. Not only will the beeps help with achieving the perfectly timed round, but there is now a vibration buzzer as well. Both vibration and sound can be switched off individually. The new watch comes with a USB charger for the rechargeable battery needed to power the vibe and the louder sound! These new watches will also come in the 7 popular colours.

OS Series 14 - Revolutionary Optimum Time sailing watches!!!!
October 2013

NEW OE390The waiting is nearly over! The release of the eagerly awaited OS Series 14 is near. This new watch is just 4mm bigger in diameter than the Series 3. That small increase has allowed for a large circular display that uses dot matrix technology. Under normal use, the sailing countdown is visible in legendary big OT digits. However, for the last 59 seconds the display comes alive to a massive 25mm. None of the world-famous features are lost, but buttons around the outside of the watch make them much easier to press with gloves on. The RED OS 1436 will also be capable of displaying sailing countdown and real time at the same time. This should be a big hit with race officers. If that is not enough, the OS 1450R white, OS 1454R blue and OS 1455R yellow will all come with a rechargeable battery and USB charger clamp. This extra power means we have been able to include a vibration buzzer to add to the louder alarm sound. Both vibration and sound can be switched off individually. Forget the rest - buy the best featured new sailing watches on the market!!!

October 2013

NEW OE390The new version of the classic event watch has now landed in the UK. The OE Series 380 event watches will still be as reliable as ever, and the interest in the coloured range has made it an instant success. Optimum Time has not stood still, and has improved the electronics of the product & improved static electricity protection. At the same time, the chip has been changed to give even better battery life, while adding improved eventing functions. These are the OE Series 390. Now the countdown timer gives an audible warning every full minute to go, plus a last 30 second beep sequence that warns of the end of period. Count-up from is still available with minute warnings, but the new big feature is programmable count-up. Put in the course time, press start, then see as the watch heads for that time – still with a beep every minute gone, but with a last 30 second warning beep sequence. Don't forget, this is the model that will also include PINK!

New OS314 launched (and sneaky preview of OS319)
September 2013

NEW OS 314It's here now. The "Big Yellow Sailing Watch" has always had a big following in sailing. The must-have item became available in the spring in white. Following the success of a colour choice, it was decided to expand the range. For years Ronstan bought a blue version from OT and sold it under its own brand. That agreement is over, so the "Big Blue Sailing Watch" is now available from OT – where it belongs – in the Optimum Time Brand of specialist sports timers. Watch out for pink – by popular demand – at the end of October 2013.
