A proper mechanical chronograph with real horological pedigree. The Tophill TL030G is powered by the Seagull ST1901 — the celebrated column-wheel, hand-wound chronograph movement descended from China’s original 1960s pilot’s chronograph. You wind it by hand, press the pusher, and a central hand sweeps the elapsed seconds; it’s the kind of watch enthusiasts seek out, not just another quartz chrono.
The dial is a vintage-style multi-scale layout: a running-seconds sub-dial at nine, a 30-minute counter at three, and a telemeter scale around the edge for gauging distance by sound (start at the flash of lightning, stop at the thunder, read the kilometres). It comes in matte blue, matte white or matte black, each with an oil-pressed textured finish, pencil hands and C3 green lume for low-light reading. Flip it over and the display caseback shows the column-wheel movement at work.
The 316L stainless steel case is a classic 40 mm (48 mm lug-to-lug, 11.85 mm thick) under a flat sapphire crystal, on a premium quick-release textured cowhide strap. It’s a limited edition — a small run per colour — and backed by a 3-year warranty.

Rated 50 m (5 ATM): fine for handwashing and rain, but not for swimming, showering or submersion — and never operate the crown or pushers in water. It’s a hand-wound mechanical, so wind it each morning (about 30 turns) to keep it running; the chronograph pushers start, stop and reset the central seconds hand. Wipe with a soft cloth, keep the leather strap dry, and keep away from strong magnets.
Is it automatic or hand-wound?
Hand-wound. The Seagull ST1901 is a manual-wind mechanical chronograph — wind it by hand (about 30 turns) and it runs ~50 hours. It does not self-wind.
What’s special about the ST1901?
It’s a genuine column-wheel chronograph movement descended from China’s original 1960s pilot’s chronograph — smoother and more collectible than the cam-and-lever chronographs at this price.
What is the telemeter scale for?
It measures distance by sound: start the chronograph at a flash (lightning, a starting gun) and stop it at the sound, then read the approximate distance in kilometres.
Is the crystal sapphire?
Yes — a flat sapphire crystal on the front, with a transparent display caseback.
Can I swim with it?
No. It’s rated 50 m for splashes and handwashing only — not for swimming, showering or diving.

Return Policy
Tophill offers a 3-year warranty on its watches, please buy with confidence.
Your warranty is valid for policy use only. Damage not caused by the quality of the product itself and belonging to one of the following conditions cannot be warranted.
1. Exceeding the warranty period.
2. Human damage, accidental impact or fall, etc..
3. Wear and tear, scratches, discolouration of external parts during normal use.
4. Damage caused by maintenance, disassembly or modification of the watch without the authorisation of the brand.
5. Quartz watch battery depletion.
6. Damage caused by exterme environmental use, extremely high/low temperatures.
7. Diving watch not drained of helium in accordance with the operating instructions resulting in the bursting of the crystal.
8. Continuous use of mechanical watches under high-frequency vibraion environment (e.g. electric drill operation).
Water Resistance
Watches rated for standard water resistance (30–50 meters) are designed to withstand only splashes and rain under conditions of minimal water pressure. Please refrain from swimming or diving while wearing such a watch, as increased water pressure may cause water to penetrate the timepiece. Furthermore, water-resistant watches should not be exposed to warm water, used in bathrooms, or subjected to environments with rapid temperature fluctuations; doing so accelerates the aging of the watch’s sealing materials and compromises its water-resistant performance. If condensation or water vapor appears beneath the watch crystal, it indicates that water has already entered the watch. In such cases, please find a watch repair center immediately to undergo a water-resistance test and replace the necessary sealing components to prevent water damage to the movement.
Shock Resistance
A watch is a precision instrument. While the minor vibrations encountered in daily life will not affect the normal operation of the movement, vigorous physical activity or severe impacts may exceed the movement’s tolerance limits and result in damage to the watch. Therefore, it is advisable to remove your watch during strenuous physical activities; additionally, you should generally avoid subjecting the watch to severe shocks or impacts.
Anti-Magnetism
Watches should not be brought into contact with, or placed in close proximity to strong magnetic fields. If the watch is worn near objects generating strong magnetic fields, such as generators or electric motors, or if it is inadvertently placed near radios, televisions, audio systems, or other magnetic sources, it may become magnetized. Once magnetized, the watch’s timekeeping accuracy will be compromised, and in some cases, the watch may even stop running entirely. Should this occur, the watch must undergo immediate demagnetization treatment to restore it to normal working order.
Battery
Tophill watches typically utilize high-quality original batteries. Under normal usage conditions, these batteries have a lifespan of over two years, with some models offering a battery life exceeding five years. Since a certain amount of time elapses during the shipping and retail phases of newly purchased watches, we guarantee that the battery in any new Tophill watch will function normally for at least one year from the date of purchase. Some Tophill watch models feature a low-battery warning function. If the second hand begins to skip ticking only once every few seconds, it indicates that the battery power is nearly depleted and requires replacement as soon as possible. When the battery power is running low, please ensure it is replaced promptly with a suitable new battery to prevent potential damage to the watch movement caused by battery electrolyte leakage.
Temperature
The optimal operating temperature range for a watch is between 5°C and 35°C. Exposure to temperatures outside this range may temporarily affect the watch’s timekeeping accuracy; however, once the watch returns to a normal temperature environment, its accuracy will be restored. Temperatures below -10°C or above 50°C can have a significant impact on the watch, potentially leading to timekeeping inaccuracies or even causing the watch to stop running. Temperatures exceeding 50°C may result in battery leakage or a shortened battery lifespan. Therefore, please avoid using the watch for extended periods in environments with extremely low or high temperatures.
Storage
For mechanical watches that are being stored for a long period without being worn, they should be wound once a month to prevent the movement from remaining in a static state for too long, thereby ensuring the continued operational performance of the mechanism. For quartz watches being stored for a long period, the battery should be removed promptly to prevent power depletion and potential leakage that could damage the movement; alternatively, the crown can be pulled out to the first or second position (the position where the second hand stops moving) to conserve battery power.
